System Maintenance
Revised: April 5, 2007, OL-14675-02
Much of the system maintenance information for the MARS Appliance is provided exclusively in the Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System.
The MARS Appliance requires little maintenance. To perform maintenance tasks, you can use the CLI or the web interface as needed. Some hardware maintenance tasks require physical access to the MARS Appliance.

Setting Runtime Logging Levels
To set the appliance's runtime logging levels, navigate to Admin > System Maintenance > Set Runtime Logging Levels. For typical use, it is best to leave this page set to its defaults.
When you have made your selections, click the Change Logging Levels button.
The following log levels are available:
•
Fatal. Enables fatal logging messages. Fatal messages record very severe error events that will likely lead the application to abort.
•
Error. Enables error and fatal logging messages. Error messages record error events that might still allow the application to continue running.
•
Warn. Enables warning, error, and fatal logging messages. Warning messages record potentially harmful situations.
•
Info. Enables informational, warning, error, and fatal logging messages. Informational messages highlight the progress of the application at coarse-grained level.
•
Debug. Enables debug, informational, warning, error, and fatal logging messages. Debug messages record fine-grained informational events that are most useful to debug an application.
•
Trace. Enables trace, debug, information, warning, error, and fatal logging messages. Trace messages record finer-grained informational events than debug messages.

Retrieving Raw Messages
You can retrieve raw messages from either an archive server (see Configuring and Performing Appliance Data Backups, page 6-25) or from the local files (database in 4.2x and earlier) running on the Local Controller. These two method offer different advantages:
•
Archive server. Retrieving raw messages, or event data, from an archive server is much faster than retrieving from the database. Therefore, it is the recommended option if it is available and it covers the time period you are investigating. However, this option is only available if you have enabled data archiving and waited the requisite time for the initial archival operation to occur; it is a scheduled operation that runs nightly around 2:00 a.m. Once the initial archive is performed, the event data is written to the archive server frequently, often within 5 to 8 minutes after the MARS Appliance receives the message. That data is not archived in real-time identifies another limitation to this option, and that is the historical period that can be studied. If you need to view data that is more current than an hour old, you should select the Database option to ensure that correct data is retrieved. For all other periods, the archive server option is recommended. To enable archiving, see Configuring and Performing Appliance Data Backups, page 6-25.
•
Local Files (was Database in 4.2.x and earlier). Retrieving event data from the local files provides slower performance than the archive server. However, it provides access to the most current data received. When you select this option, you can specify where you want the retrieved records to be written: in the default local directory or the a remote server, if one is available.

About Raw Message Size Limitations and Storage Location
Prior to the 5.2.4 release, the storage of raw message data in the local database was restricted to 500 KB per message. Beginning with 5.2.4, the raw message size is stored in local files that can be up to 1.5 MB without being truncated. Each MARS Appliance model has dedicated disk space reserved for arbitrary-sized raw message files. When the upper limit of this storage size is reached, the pnarchiver process moves the raw messages and assocaited index files to the remote NFS server, if configured. If not NFS server is configured, then the raw message files are purged, oldest data first (first in, first out). When the database is purged, the corresponding raw message files are also purged.
The raw message files are archived under /pnarchive/DATA_POOL. These the DATA_POOL directory contains a dated directories under which the raw message files created on that date are compressed and saved. An example /pnarchive/DATA_POOL/<date> directory listing follows:
The file names use the following format:
[dbversion]-[productversion]-[serialno]_[StartTime]_[EndTime].gz
For example, the ./pnarchive/DATA_POOL/2007-02-12/ES listing reveals:
ix-5248-524-1171238692_2007-02-12-00-04-46_2007-02-12-01-04-51.gz
rm-5248-524-1171238692_2007-02-12-00-04-46_2007-02-12-01-04-51.gz
Note
Those files beginning with "ix" are index files, and those beginning with "rm" are the raw message files.
Retrieve Raw Messages From Archive Server
Use this selection if archiving is enabled.
To retrieve event data from an archive server, follow these steps:
Step 1
Click Admin > System Maintenance > Retrieve Raw Messages.
Figure 26-2 Retrive Raw Messages Page (4.2.x)
Figure 26-3 Retrive Raw Messages Page (5.2.x)
Step 2
Specify the time range by specifying values in the Start and End fields.
Step 3
Verify that Retrieve Data From Archived Files is selected.
The data will be retrieved from the server identified under Admin > System Maintenance > Data Archiving.
Step 4
Click Submit.
Note
While MARS is generating your files, you can still use the system for other tasks.
Result: The Retrieving Progress 0% screen appears. When the operation is complete, the Raw Message Files screen appears, identifying a new Gzip archive file with a filename based on specified time range.
Step 5
To download and view the generated raw message file, click Click Here to Download next to the filename.
The filename adheres to the following syntax: YYYY-MM-DD-HH-MM-SS_YYYY-MM-DD-HH-MM-SS.gz.
Step 6
Use WinZip or another archive expansion program to extract the contents of the Gzip archive file.
Step 7
Once the textfile is extracted from the GNU Zip archive format, its contents resemble the following:

If you see Chinese or other unfamiliar characters in the resulting text file, please use Microsoft Internet Explorer to view the file and verify that the Western European ISO or Western European Windows encoding value is selected (View > Encoding). The "»" sign appears correctly as a separator when a compatible encoding is selected.
Retrieve Raw Messages From a Local Controller
Use this selection if archiving is not enabled or if you need to view event data that was received within the past hour.
Note
For versions prior to 5.2.4, raw messages are retrieved from the database. Begining with the 5.2.4 release, event data is stored in local files that allow for raw messages up to 1.5 MB.
To retrieve event data from the Local Controller, follow these steps:
Step 1
Click Admin > System Maintenance > Retrieve Raw Messages.
Figure 26-4 Retrive Raw Messages Page (4.2.x)
Figure 26-5 Retrive Raw Messages Page (5.2.x)
Step 2
Specify the time range by specifying values in the Start and End fields.
Step 3
Select Retrieve from Local Files. (This option was Retrieve Data from DB in 4.2.x and earlier.)
Step 4
Select one of the following options:
•
Save to Local. This option retrieves the data from the local files (or database in 4.2.x and earlier) and stores it on the local appliance.
•
Save to Remote. This option retrieves the data from the local files (or database in 4.2.x and earlier) and stores it on the archive server, as identified under Admin > System Maintenance > Data Archiving.
Step 5
Review the Cached Files time range information, and then do one of the following:
•
If you want data from within this time range, you do not need for Force Generate Files.
•
If you want data that does not fall within the Cached Files time range, select the Force Generate Files check box.
•
If there is no cached file information, select the Force Generate Files check box.
If no cached file data is shown, then no previous queries have been performed and stored. For example, if you preform three separate queries, using time range A, from the local files (or database in 4.2.x and earlier) using the time range, saving the files to the local MARS Appliance. If you later specify the same time range A and do the retrieval again but you do not clear the Force generate files check box, the system performs the query, generating the file again. However, if you have already retrieved and stored some data before, you can specify to retrieve them from those saved files by clearing the Force generate files check box.
Step 6
Enter the maximum number of retrieved files to retain in the Maximum No. of Files field.
This value refers to the maximum number of event files to be generated for this query.
Note
Requesting large numbers of files can take some time.
Step 7
Select the list of devices for which you want to pull event data in the Reporting Devices list.
You can select a specific device by name or All Devices.
Step 8
Click Submit.
Note
While MARS is generating your files, you can still use the system for other tasks.

Change the Default Password of the Administrator Account
Good security practices require that you change the default password. We recommend using strong passwords for the MARS Appliance appliances.
Login names and passwords:
•
can be alphanumeric characters
•
are case sensitive
•
can contain special characters (!, @, #, etc.)
•
cannot contain single or double quotes (`or ")
Login names can contain up to 20 characters. Passwords can contain up to 64 characters.
To change the default password and setup administrator notification, follow these steps:
Step 1
Click the Management > User Management tab.
Step 2
Check the box next to Administrator, and click Edit.
Step 3
Enter the new Administrator password and the Administrator e-mail address.
Step 4
Click Submit.
Understanding Certificate and Fingerprint Validation and Management
Many reporting devices use certificates or fingerprints to enable secure communications over SSL or SSH respectively. Beginning in 4.2.3, MARS performs a strict check of the certificate or fingerprint of the device or server to which it is attempting to connect.
Note
Certificate validation does not follow the convention of presenting the client with a list of certificate authorities and using the selected one to validate individual certificates. Instead, the MARS Appliance compares the certificate presented by the reporting device with a previously stored instance of the certificate. If the two match, the presented certificate is considered valid. This approach allows MARS to validate certificates without knowledge of revocation lists and to operate in a network without an Internet connection.
Three options exist for specifying how MARS should respond during attempts to establish a secure connection. The three options are as follows:
•
Automatically always accept. This option, which is compatible with previous releases, allows a MARS Appliance to connect to reporting devices regardless of how frequently the certificate or fingerprint changes because MARS automatically accepts and stores the replacement certificate or fingerprint for all devices. However, this option does not provide an opportunity to inspect and authorize the changes to the certificates or fingerprints. When a conflict is detected or when a new certificate or fingerprint is accepted, the event is logged to the internal log. The internal log entry includes the name of the process that detected the conflict and the IP address of the reporting device. The logs can be retrieved by queries and reports. See Monitoring Certificate Status and Changes for more information on studying these events.
•
Accept first time and prompt on change (default). This option accepts and stores a new certificate or fingerprint the first time MARS Appliance connects to a device. For subsequent connection attempts, the appliance checks the presented certificate or fingerprint against the stored value. If a conflict is detected, the session is refused unless the new certificate or fingerprint is manually accepted by the administrator. This option enables initial topology discovery to proceed without administrator intervention. Internal system logs of the initial acceptance, conflict detection, and acceptance of new change are created. The internal logs include the name of the process that detected the conflict, the IP address of the reporting device, and the username of the account used to accept the change.
If, when a change is detected by a web interface process, the session times out before administrative intervention, the communication fails but no internal system log is generated to record the failure to accept the changed certificate or fingerprint. Also, if a back-end process initiates the request, such as auto discovery, then the session attempt always fails and no attempt to obtain administrative acceptance is initiated. In such cases, any data the MARS Appliance would normally ascertain from the device during such a session is not collected. This delay of data retrieval does not apply to syslogs forward to the MARS Appliance by the reporting device and it resumes once the new certificate is accept. The recommended method for manually kicking off the change detections is to use the Test Connectivity or Discover button on the reporting device.
•
Always prompt on new and changed. This options requires an administrator to manually accept the certificate or fingerprint before MARS can establish the desired communications each time the certificate or fingerprint changes. During changes, the internal log includes the username of the account used to accept the change. If the communication times out before administrative intervention, the communication fails and an internal system log records the failure to accept the changed certificate or fingerprint.
The implication of each option varies based on which MARS service is attempting the connection, not in the enforcement of the option, but in the ability of the service to prompt for immediate administrative intervention. In other words, if the service is a GUI-based services, you will be prompted to accept the changed certificate or fingerprint. If the service is a backend service, the communications with the target device will fail and the event will be logged.
The following services and operations are affected by the global certificate/fingerprint response setting:
•
Upgrade (SSL). When MARS uses the HTTPS option to download the upgrade package from the remote server specified on the Admin > System Maintenance > Upgrade page.
•
Discovery operation. (SSH)
•
Test Connectivity operation. (SSL)
•
Cisco IDS, IPS, and IOS IPS router Event Processing (RDEP or SDEE over SSH)
•
CSM Policy Query Integration (SSL)
•
Qualys Report Discovery. (SSL)
•
Graphgen process for mitigation operation (SSH and SSL)
•
Device Monitor process for resource monitoring feature (SSH)
•
DTM process (SSH)
Setting the Global Certificate and Fingerprint Response
The default response is to accept the certificate or fingerprint the first time MARS attempts to connect to the device, after which if a conflict is detected, then administrative intervention is required to update to the new certificate or fingerprint.
If this option is not the one that you wish to use, you can select from three options. The global setting for the conflict detection responses is located on the Admin > System Parameters > SSL/SSH Settings page.
To change the default certificate and fingerprint response, follow these steps:
Step 1
Log into the web interface using an account with Administrative privilege.
Step 2
Click the Admin > System Parameters > SSL/SSH Settings.
Step 3
Select one of the following options to define the global behavior that you require:
•
Automatically always accept
•
Accept first time and prompt when changed
•
Always prompt on new and changed
For details on these options, see Understanding Certificate and Fingerprint Validation and Management.
Step 4
Click Submit.
Upgrading from an Expired Certificate or Fingerprint
If you have selected a global response option other than Automatically always accept (see Setting the Global Certificate and Fingerprint Response), you will at some time be required to update an expired certificate or fingerprint.
Two options exist for upgrading from an expired certificate or fingerprint. If you are logged in to the web interface when a GUI process detects a certificate or fingerprint conflict, you will be prompted to accept or reject the new value. Otherwise, if you are not logged in or a backend process detects the conflict, you must manually initiate a communication with the device. To determine the list of devices for which you must manually update the certificates or fingerprints, review the Activity: CS-MARS Detected Conflicting Certificates/Fingerprints report (see Monitoring Certificate Status and Changes).
The following procedures explain how to upgrade under the specific circumstances:
•
Upgrade a Certificate or Fingerprint Interactively
•
Upgrade a Certificate Manually
•
Upgrade a Fingerprint Manually
Upgrade a Certificate or Fingerprint Interactively
An interactive upgrade refers to responding to a web interface prompt to update the certificate. This type of upgrade is available when you are logged into the GUI and a process, such as graphgen, prompts you to upgrade a certificate or fingerprint that conflicts with the previously accepted value. Click Yes to accept the new fingerprint or certificate.
Upgrade a Certificate Manually
A manual upgrade allows you to upgrade any certificate at any time due to any reason: session time out during interactive prompt, user error, detection of conflict by a backend process.
To manually upgrade to a new certificate, follow these steps:`
Step 1
Log into the web interface using an account with Administrative privilege.
Step 2
Select the reporting device on the Admin > System Setup > Security and Monitor Devices page for which MARS has detected a certificate conflict. and click Edit.
Step 3
Click Test Connectivity.
The dialog box displays stating "Do you want to accept following certificate for the device named: <device_name>?.
Step 4
Verify the certificate value.
Step 5
If the value is correct. click Yes.
Upgrade a Fingerprint Manually
A manual upgrade allows you to upgrade any fingerprint at any time due to any reason: session time out during interactive prompt, user error, detection of conflict by a backend process.
To manually upgrade a fingerprint, follow these steps:
Step 1
Log into the web interface using an account with Administrative privilege.
Step 2
Select the reporting device on the Admin > System Setup > Security and Monitor Devices page for which MARS has detected a fingerprint conflict and click Edit.
Step 3
Click Discover.
The dialog box displays stating "Do you want to accept following fingerprint for the device named: <device_name>?.
Step 4
Verify the fingerprint value.
Step 5
If the value is correct, click Yes.
Monitoring Certificate Status and Changes
To support the certificate management features in MARS, the following system inspection rule exists:
•
System Rule: CS-MARS Failure Saving Certificates/Fingerprints. This inspection rule indicates that MARS has failed to save a new or changed device SSL certificate or SSH key fingerprint based on either explicit user action or automatic accept as specified on the SSL/SSH Settings page.
In addition, the following reports appear under the System: CS-MARS Issue category.
•
Activity: CS-MARS Accepted New Certificates/Fingerprints
•
Activity: CS-MARS Accepted Conflicting Certificates/Fingerprints
•
Activity: CS-MARS Detected Conflicting Certificates/Fingerprints

Replacing the RAID Battery Backup Unit
This section pertains only to the MARS 110R, 110, 210, GC2R, and GC2 appliances.
RAID Controller Back-Up Battery
Part number: CS-MARS-X10-BB=
The RAID Backup Battery Unit (RAID BBU) prevents RAID data loss by preserving data held in the RAID cache module during a power outage. The RAID BBU can provide up to 72 hours of battery power until the system power is restored.
The RAID BBU requires 24 hours to fully charge from when the appliance is first powered on, and is continually charged thereafter from the system power. The total charge capacity of the battery degrades over time. The show healthinfo CLI command reports the relative charge state of the RAID BBU.
There is a direct relationship between the relative charge and the battery backup time
(100%charge = 72hours ). A 100 percent charge provides 72 hours RAID cache protection. Similarly, a 75 percent charge provides 54 hours of protection (100%charge * .75 = 72hours * .75).
Make sure there is sufficient charge to provide RAID cache protection for the total probable hours the MARS Appliance could be without system power. For example, a 90.3% charge (65 hours) would allow 2 hours to manually restore system power if a total power outage occurred in an unattended facility between 17h00 Friday to 8h00 Monday (63 hours).
Example 26-1 displays BBU status information in an excerpt of the show healthinfo CLI command.

Except for the MARS 55, the MARS RAID controller cards operate the hard drives in a RAID 10 configuration, also called RAID 1+0 because it combines the data handling techniques of RAID 1 and RAID 0. The MARS 55 operates as RAID 1 only. For additional information on RAID concepts and terminology, access the following URL: http://en.wikipedia.org/wiki/RAID
RAID 0 Data Striping
In a MARS RAID 10 configuration, half the total number of drives are arrayed as a single logical drive, wherein a data block is distributed across all of the physical drives in the logical drive using RAID 0 striping techniques. Data striping results in better performance for a data intensive application such as MARS, because hard drive random access times are minimized when data is read and written simultaneously from more than one physical hard drive.
Note
The MARS 55 does not do RAID 0 striping. It is RAID 1 only.
RAID 1 Mirroring and Subunits
Half the number of drives in the MARS RAID 10 array mirror the RAID 0 virtual drive. Each physical drive in the RAID 0 array is mirrored by an identical physical drive using RAID 1 techniques. Data written to one of the drives within the RAID 0 array is simultaneously written to its dedicated RAID 1 partner, thereby providing fault tolerance through data redundancy. The RAID 1 hard drive pairs are listed in Table 26-4. For the MARS 55, one drive mirrors the other in a simple RAID 1 configuration.
Rebuilding a Degraded Array
Either drive in a RAID 1 pair can serve in place of its partner should either drive become degraded (unavailable, physically inoperative, or data corrupted). A physical drive degraded but still physically operative can be rebuilt from the data of its undegraded partner and rejoin the array. An inoperative physical drive can be replaced with an operative one which is then rebuilt to join the array.
When any physical drive of the RAID 10 array is degraded, the entire array is considered degraded. While the array still functions, it is not working to its optimal throughput or redundancy capacity.
In a degraded RAID 10 array, data destined for a degraded physical drive is written to available space on the RAID 1 partner until the degraded drive can be rebuilt or replaced. Degraded drives are rebuilt in sequence, one rebuilding process must complete before the next process can begin. Between 200 and 300 minutes are required to rebuild a RAID 1 subunit.
Hotswapping Hard Drives
This section pertains only to the MARS 55, 110R, 110, 210, GC2R, and GC2 appliances.
An HDD can be hotswapped, that is, replaced without rebooting the MARS appliance. The hotswap actions can be summarized in the following five steps. The detailed procedure is in the section, Procedure to Hotswap a Hard Drive.
1.
Establish a console connection to the MARS appliance.
2.
Enter the raidstatus command to determine the status and the chassis HDD slot number of the HDD to hotswap.
3.
Execute a hotswap remove disk command, then remove the HDD.
4.
Execute a hotswap add disk command then insert the replacement HDD.
5.
Enter the raidstatus command to monitor the progress of the replacement HDD as it is rebuilt.
Use the raidstatus CLI command to view the status of the RAID array (virtual disk) and of the individual HDDs. Table 26-2 lists the status conditions that require an HDD to be hotswapped. These status conditions cause MARS to send an email alert to the adminstrator.
Caution 
Always use the
hotswap remove disk CLI command before you remove a hard drive and
hotswap add disk before you insert a hard drive. The
disk argument is the hard drive slot number.
Use the
hotswap list all command to view the slot number to Port and PD number map.
The rebuilding process duration is between 200 and 300 minutes, depending on CPU load.
Note
To match original performance, hotswapped HDDs should be the same make, model and size as the original HDDs.
Caution 
The RAID 10 array will not function if both both HDDs of any RAID 1 pair are removed or corrupted.

Procedure to Hotswap a Hard Drive
This section pertains only to the MARS 55, 110R, 110, 210, GC2R, and GC2 appliances.
In the hotswap command, the disk parameter is the chassis slot number of the HDD, but the raidstatus command reports physical drive (PD) numbers or Port numbers (MARS 55). To determine the physical location of the slot in the chassis (chassis slot number), see Figure 26-12 or Figure 26-13 or use the hotswap list all command.
To hotswap an HDD, complete the following steps:
Step 1
Remove the front bezel. See the "Removing and Replacing the Front Bezel" section.
Step 2
Establish a console connection with MARS.
Step 3
Identify the slot number of the HDD to replace with the raidstatus command.
Step 4
Enter hotswap remove disk. (where disk is the slot number of the HDD)
A message informs you that it is safe to remove the HDD.
Note
Make sure that you remove the correct physical HDD. If you remove the wrong one accidently then reinsert it, that HDD will register as Unconfigured Good (or Failed for MARS 55).
Step 5
Pull out the black lever of the hard drive carrier and slide the carrier from the chassis as shown in callout B of Figure 26-14.
Figure 26-14 Removing a Hard Drive from the MARS Appliance Chassis
The raidstatus command should now report the slot status as N/A (or Failed for MARS 55).
Step 6
At the CLI prompt, enter hotswap add disk . Be sure to use the same slot number as in Step 2.
Step 7
With the black lever in the fully open position, slide the replacement HDD and carrier into the chassis. The green latch at the front of the drive carrier must be to the right. Do not push on the black drive carrier lever until the lever begins to close by itself.
Step 8
When the black drive carrier lever begins to close by itself, push it closed to lock the drive assembly into place.
A console message informs you that the HDD (disk) is added successfully (to the logical array).
Step 9
Replace the front bezel. (See "Removing and Replacing the Front Bezel" section).
Step 10
From the CLI, enter raidstatus to verify that the HDD is being rebuilt into the RAID array.
The status message indicates the progress of the added HDD.
The rebuilding process can last from 200 to 300 minutes.
End of Procedure, Hotswapping Hard Drives.

To avoid the possibility of coming into contact with hot component(s) during a hot-plug installation, be careful when removing or installing the hot-plug component(s).
Caution 
To avoid injury do not contact moving fan blades. If your system is supplied with a guard over the fan, do not operate the appliance without the fan guard in place.
Rack Mount Warnings
The equipment rack must be anchored to an unmovable support to prevent it from tipping when a server or piece of equipment is extended from it. The equipment rack must be installed according to the rack manufacturer's instructions.
Install equipment in the rack from the bottom up, with the heaviest equipment at the bottom of the rack.
Extend only one piece of equipment from the rack at a time.
You are responsible for installing a main power disconnect for the entire rack unit. This main disconnect must be readily accessible, and it must be labeled as controlling power to the entire unit, not just to the appliance.
To avoid risk of potential electric shock, a proper safety ground must be implemented for the rack and each piece of equipment installed in it.
Electrostatic Discharge (ESD)
Caution 
ESD can damage disk drives, boards, and other parts. We recommend that you perform all procedures at an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground -- any unpainted metal surface -- on your server when handling parts. Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After removing a board from its protective wrapper or from the server, place the board component side up on a grounded, static free surface. Use a conductive foam pad if available but not the board wrapper. Do not slide board over any surface.
Battery Replacement
Caution 
Do not attempt to recharge a battery. Do not attempt to disassemble, puncture, or otherwise damage a battery.

Cooling and Airflow
Carefully route cables as directed to minimize airflow blockage and cooling problems. For proper cooling and airflow, operate the system only with the chassis covers installed. Operating the system without the covers in place can damage system parts.
To install the covers:
•
Check first to make sure you have not left loose tools or parts inside the system.
•
Check that cables, add-in boards, and other components are properly installed.
•
Attach the covers to the chassis according to the product instructions.
