System Requirements

The following is the minimum hardware and software you need to install and run Cisco MNM:

Sun Fire 280R (UltraSPARC III) supporting two hard drives in a single rack-mount package; other Sun platforms in the UltraSPARC II and III families are also supported (two CPUs at 440 MHz or faster)

Sun Solaris 8 operating system

April 2001 release recommended

Open Windows with the Common Desktop Environment (CDE)

2.0 GB of RAM (or greater)

Properly configured 9 GB SCSI drives. The database drives should be configured as raw devices and connected to a separate SCSI controller for maximum performance.

The tmpfs file system must be mounted to /tmp for maximum performance.

Detailed system requirements are documented in Chapter 1 of the Cisco MGC Node Manager Installation Guide at http://www.cisco.com/en/US/products/sw/netmgtsw/ps1912/products_user_guide_list.html.

Review this chapter prior to installing or configuring the software.


Note Installing drives greater than 9 GB does not result in performance gains. The main bottleneck of the CEMF application is hard disk input/output (i/o) speed, not capacity. Maximum performance is achieved using many drives of lower capacity instead of a few, larger capacity drives.


Supported Configurations

These configurations are supported:

Cisco MGC Node Manager and Cisco VSPT installed together on a network management server. (Recommended)

Cisco MGC Node Manager installed on a network management server and Cisco VSPT installed on a Cisco PGW host machine.

Cisco MGC Node Manager installed on a network management server and Cisco VSPT installed on a separate server.


Note Other element managers may be installed on the network management server.

Known Issues and Operational Recommendations

This section contains information about known issues and the corresponding workarounds.


Note For more information about Cisco IOS issues and workarounds, see the Cisco IOS release notes for your platform.


Cisco MGC Node Manager Checks for Available Disk Space For Installation

During installation, Cisco MGC Node Manager detects how much disk space is available for installation. If the system does not have enough available disk space, you are prompted whether you want to continue the installation routine. If you enter 'N' to stop the Cisco MGC Node Manager installation, the installation continues.

The workaround is to ensure that enough free disk space is available before Cisco MGC Node Manager is installed. The amount of disk space required is detailed in the Cisco MGC Node Manager installation guide.

Cisco MGC Node Manager Cannot Discover an Interface or IP Address for BAMS

Sometimes Cisco MGC Node Manager reports that it cannot discover an interface or IP address for BAMS. This might be caused by the mib2agt getting into a strange state. You can restart the mib2agt by stopping the current process. The new process mib2agt is restarted automatically.

ps -ef | grep mib2agt

kill -9 <PID>

Hints and Tips

Initial Cisco MGC Node Manager Configuration

Cisco MGC Node Manager is initially configured with one user:

id: admin 
password: admin

Installing CEMF/Cisco MGC Node Manager on a Server

If you have installed CEMF/Cisco MGC Node Manager on a server and need to change the IP address/hostname, you must make the changes shown in the following procedure:


Note The following example uses the hostname CMNM and the IP address 10.1.1.1.



Step 1 #cd <CEMF Directory>/bin

Step 2 #./cemf stop

Step 3 Edit "/var/adm/Atlantech/system/info" to reflect the following hostname and ip address:

MGRHOSTNAME=rambler
MGRIPADDRESS=10.1.1.1
COREHOSTNAME=rambler

Step 4 Edit "<CEMF Directory>/config/env/avCore.sh" to reflect the hostname in the lines below, and save the file.

MgrSystemManager=rambler1270; export MgrSystemManager
PortAllocator=rambler1270; export PortAllocator
transRouter=rambler1271; export transRouter;

Step 5 Edit "/var/sadm/pkg/CSCOcemfm/pkginfo" to reflect the following values:

MGRIPADDRESS=10.1.1.1
MGRHOSTNAME=10.1.1.1
COREHOSTNAME=10.1.1.1
LOCALHOSTNAME=10.1.1.1

Step 6 You will also need to make these same changes for each Element Manager. To do so, edit the following files:

/var/sadm/pkg/hostEM/pkginfo
/var/sadm/pkg/mgcEM/pkginfo

Step 7 Rename "<CEMF Directory>/ODI/OS5.1/ostore/<hostname>_server_parameter" to reflect the new hostname.


Note You must obtain a new CEMF license. For information on obtaining a new CEMF license, refer to "CEMF Licensing" in the "Troubleshooting" section.


Step 8 Type <CEMF Directory>/bin/cemf start


Configuring the CEMF Software for Maximum Performance

The following are guidelines for installing CEMF:

Use the primary drive for the Solaris operating system and the ObjectStore transaction log.

The second drive should contain the CEMF software (that is, /opt/cemf).

Configure the ObjectStore database for Raw File Systems. The remaining hard drives should contain the RAW File System partitions for the CEMF database (preferably on a separate SCSI controller).

Mount the tmpfs file system to /tmp so the ObjectStore cache files can be kept in memory. ObjectStore is the database program included with CEMF. Keeping the cache files in memory provides for an enormous performance boost for CEMF. Here is how the tmpfs line should read in the /etc/vfstab file (the blank areas between the keywords are spaces):

swap  -  /tmp  tmpfs  -  yes  -

Troubleshooting

Viewing Core Files Generated by CEMF and Cisco MGC Node Manager

Use the "/opt/cemf/bin/listCores" command to view all core files generated by CEMF and Cisco MGC Node Manager.

CEMF Licensing

If you are having problems with CEMF licensing, you might need to stop and restart the license manager daemon. To do so, execute the following commands:

#>  /etc/rc2.d/S98alvm stop 
#>  /etc/rc2.d/S98alvm start

Note The CEMF licenses are fixed for a particular machine. You cannot copy the license file from one machine to another. If you want to install the CEMF software on another machine, you must contact Cisco TAC and ask for a new license. You will need the hostname and hostid of the new machine.


Viewing the Most Recently Changed Log Files

Cisco MGC Node Manager log files are stored in <CEMF Directory>/logs. You can view the most recently changed log file with ls -lt command.

Cisco MGC Node Manager Log Files

Some Cisco MGC Node Manager log files are:

hostController.log [MGC Host]

mgcController.log [MGC Node]

trapLog.log Incoming traps are logged here, to separate them from CEMF log messages collected in mgcTrapProcessor.log.

Error Messages That Are Safe to Ignore

Most of the entries in the Cisco MGC Node Manager log files are created by the CEMF platform and are of limited value. The following error messages are safe to ignore:

SNMP and MIB parsing errors (which display when an EM controller starts):

SNMP : ERROR mib.cc:1283 Mib Object is already on the tree for

SNMP : ERROR mibDependencyMgr.cc:191 mibDependencyMgr.cc:196 Mib . not defined

SNMP : ERROR mibParser.y:359 EXPORTS are currently ignored (;, line 8)

SNMP : WARN mibParser.y:1154 Name and number form OIDs are not properly implemented ().

Database warning (which display when an EM controller is first installed):

general : WARN Creating Database /opt/AV3/db/mgcController.db

General errors (which display when the EM controller starts up):

general : ERROR Unable to get event channel ID for channel ' '

general : ERROR EventChannelManager : Failed to find location for event channel

general : WARN OGManager::OGManager - Unable to get deleteEventChannel from .ini file

general : ERROR OGManager::processGroupClass - invalid class id

general : ERROR EventChannelManager : Failed to find location for event channel ERROR OGManager::processGroupClass - invalid class id

general : ERROR OGChangeEventHandler::process - could not find drep!

general : ERROR IdAllocatorOS : Deprecated constructor called

Task : WARN PerfPollTask::createGroupsResult : group . already exists.

mgcController : WARN Controller::initialiseController Controller is configured NOT to auto populate tech tree on autodiscover

Other miscellaneous errors:

general : WARN CommsBuffer::serialize - resizing buffer size

general : ERROR PersistentAttributeStore::PersistentAttributeStore() nameInit = 'xxx. is longer than 16 characters. All Objectstore segment comments will be truncated to use the first 16 characters.

Resetting the User Password

If you forget your password, you can reset the CEMF user IDs and passwords. The following command removes all passwords, and resets the admin user ID's password to administrator.

<CEMF Directory>/bin/cemf shell 
<CEMF Directory>/bin/partitioningTool -r

Backing Up and Restoring the CEMF/Cisco MGC Node Manager Databases

The following command backs-up the CEMF/Cisco MGC Node Manager databases. By default the backup files are placed in /opt/AVBackup.

/opt/CSCOcemf/bin/cemf stop 
/opt/CSCOcemf/bin/cemf backup 
/opt/CSCOcemf/bin/cemf start

The following command will restore a CEMF/Cisco MGC Node Manager database.

/opt/CSCOcemf/bin/cemf stop 
/opt/CSCOcemf/bin/cemf restore -t mm-dd-yyyy 
/opt/CSCOcemf/bin/cemf start

For more information on backing up and restoring CEMF/Cisco MGC Node Manager Databases refer to the "Cisco EMF Database Backup and Restore Procedures" section of the Installing, Licensing, and Configuring Cisco EMF Manual.

Forcing an Uninstall of an Element Manager

The CEMF daemons must be running for the Element Managers (EMs) to uninstall. There are two ways to force an uninstall of an EM; both cause loss of all CEMF/Cisco MGC Node Manager data. Before running these commands, it is recommended that you back up your databases.

The uninstallCSCOcmnm script can be invoked with an undocumented option to force the removal of all or one EM. From a command line, as root, type the command:

/opt/CSCOcemf/uninstall/uninstallCSCOcmnm -force [-em <EM>] 

You can specify only one EM to remove or all EMs by omitting that parameter. The list of EMs includes hostEM, mgcEM, andmgxEM.

Example:

/opt/CSCOcemf/uninstall/uninstallCSCOcmnm -force -em mgxEM -em mgcEM 

After you run this command, the CEMF databases are corrupted. To correct this problem, reset the CEMF databases by running the following command. You must do this before using CEMF again, even using CEMF to reinstall Cisco MGC Node Manager.

/opt/CSCOcemf/bin/cemf stop 
/opt/CSCOcemf/bin/cemf reset 
/opt/CSCOcemf/bin/cemf start

After you have successfully reset the database and restarted CEMF, you must reinstall Cisco MGC Node Manager. If you want to restore a CEMF/Cisco MGC Node Manager database after you have reinstalled Cisco MGC Node Manager, refer to "Backing up and restoring the CEMF/CMNM Databases" in the preceding section.

If the above method does not remove the EMs, then you can try another method. When the EMs are installed, Solaris package information is placed in subdirectories of "/var/sadm/pkg". The subdirectory is the name of the package, as specified above (that is, hostEMm, mgcEMm, and so on). As the root user, complete the following steps for each EM that you want to remove.

/opt/CSCOcemf/bin/cemf stop 
touch /var/sadm/pkg/<EM>/install/.avload 
pkgrm <EM> 
/opt/CSCOcemf/bin/cemf reset 
/opt/CSCOcemf/bin/cemf start

Example:

/opt/CSCOcemf/bin/cemf stop 
touch /var/sadm/pkg/mgcEMm/install/.avload 
pkgrm mgcEMm 
/opt/CSCOcemf/bin/cemf reset 
/opt/CSCOcemf/bin/cemf start

To restore a CEMF/Cisco MGC Node Manager database after you have reinstalled Cisco MGC Node Manager, refer to the preceding "Backing Up and Restoring the CEMF/CMNM Databases".

Managing Network Devices Over a Slow Link

If you are managing network devices over a slow link (T1 or slower), you might need to alter SNMP parameters used by Cisco MGC Node Manager for SNMP Get Requests. You can change these parameters for any existing objects by accessing the States dialog. You can also change these parameters in the Advanced tab of the Seed File Deployment dialog.

The default number of SNMP retries is 2. You might need to increase this value when the Cisco MGC Node Manager workstation is connected to network devices over a slow link.

The default SNMP timeout value is 5000 milliseconds (5 seconds). You may need to increase this value when the Cisco MGC Node Manager workstation is connected to network devices over a slow link.

Maximizing Logfile Output

By default Cisco MGC Node Manager logs only warning and error messages. If you want to turn on debug messages in all log files, complete the following steps, as the root user:


Step 1 cd <CEMF Directory>/bin

Step 2 Type ./cemf stop

Step 3 cd <CEMF Directory>/config/init

Step 4 Edit loggercommon.include and add or change the following line:

loggingLevelMask = 12

Step 5 cd <CEMF Directory>/bin

Step 6 Type ./cemf start

Step 7 Add r change the following line to set the logging level back to warning,

loggingLevelMask = 10
