Upgrade Procedure

Upgrading SCMSA from CWM 15 or 15.1.50 Running Solaris 8 with Multiple SCM Gateways

Upgrading the Standalone Statistics Collection Manager

This chapter provides step-by-step procedures to upgrade to a Standalone Stats Collector on a Solaris 9 platform.

Statistics Collection Manager Standalone (SCMSA) permits the statistics standalone machines to consist of one of these configurations:

•A standalone Statistics Manager and Statistics Collector (SSM)

•A standalone Statistics Collector (SSC).

Note The standalone parser configuration in Release 11 and Release 10.5 is not allowed in CWM 15.3.00.

The following upgrade paths are supported.

•CWM 15.1.50 (latest patch) on Solaris 9 to CWM 15.3 on Solaris 9

•CWM 15.1.50 (latest patch) on Solaris 8 to CWM 15.3 on Solaris 9

•CWM 15.0 (latest patch) on Solaris 8 to CWM 15.3 on Solaris 9

This release of SCMSA is supported only on the Solaris 9 platform. If you upgrade from a version earlier than SCMSA 15.0.00, SCMSA must first be upgraded to either SCMSA 15.0.00 or 15.1.50 and then upgraded to the current SCMSA release.

As a first step, you must decide which statistics databases, if any, are to be preserved throughout the upgrade procedure. After you have decided this, follow the procedure for preserving databases in the next section.

Caution If you will be preserving databases, these databases must be saved before any other upgrade procedures are performed.

Preserving Databases

The end result of an upgrade is always a machine with a Standalone Statistics Collector or a Standalone Statistics Manager configuration. The precise steps that are required to perform the upgrade depend upon the starting configuration. This could be one of several different configurations as described in the previous paragraph and which databases are to be preserved.

Preserving scmdb Data

An scmdb database exists in the starting configuration. However, if you are upgrading from CWM 15.0.00 or 15.1.50 and from Solaris 8 to Solaris 9, the database will be destroyed when Solaris is upgraded. In this case, the database must be saved to a safe place as a first step if it needs to be preserved, it is then restored as part of the upgrade procedure. To save the database, perform the following procedure.

The following procedure is required only when you are upgrading from Solaris 8 to Solaris 9. The procedure must be performed before attempting to upgrade Solaris or SCMSA.

Step 1 Log in on the starting Solaris 8 statistics collection machine as user svplus.

Step 2 Stop the CWM core processes if not already stopped.

Step 3 Create a directory to hold the saved Informix database.
host% mkdir <save_database_directory>

Caution Do not create the directory under the /usr/user directory. The directory should be on a separate NFS-mounted disk. If an NFS-mounted disk is not available, the directory can be on one of the CWM server disks, but the exported files must be FTPd to another system before Solaris is installed

Step 4 Change its permissions of the directory:
host% chmod 777 <save_database_directory>

Step 5 Change the current directory to the <save_database_directory> directory:
host% cd <save_database_directory>

Step 6 Verify enough disk space is available for the Informix OnLine database:
host% onstat -d

Step 7 Execute the dbexport command:
host% dbexport -o <save_database_directory> <database_name>

Use scmdb as the database_name.

Step 8 Copy the scmsa.version file (located in the /usr/users/svplus/etc directory) and the process.conf file 9 (located in the /usr/users/svplus/config directory) to the same <save_database_directory> directory.

Step 9 Copy any configuration files (such as network.conf) that should be saved to the same <save_database_directory> directory.

If the <save_database_directory> directory is on a separate NFS mounted disk, no further steps are necessary.

If the <save_database_directory> directory is on the CWM, it must be transferred to an external location. For example, saved to a tape using the tar cvf /dev/rmt/0 command or by using the FTP facility to copy to another machine.

The scmdb database and other saved files are now saved to a safe location.

Note In SCMSA 15.3.00, an exported database can only be imported back to the same machine from which it was exported. It cannot be imported from a different host machine.

Preserving statsdb Data

A statsdb database will exist on the machine to be upgraded if that machine contains a parser module. The statsdb data can be preserved by executing a script (statsdbunload.csh) that is included on the SCMSA CD. This script creates a directory that contains the statsdb data. The user then stores the directory in a specified safe place.

If the upgraded machine is to be configured as an SSM, the database is restored to that machine during the upgrade procedure.

If the upgraded machine is to be configured as an SSC it does not include the statsdb database. Therefore, later, when the CWM server upgrade process takes place, the statsdb database is located as part of the upgrade procedure and incorporated into the CWM server's database.

To save the database, perform the following procedure.

Note The following procedure is required only when upgrading from a configuration that includes the Parser.

This procedure needs to be coordinated with the upgrade of the CWM server and any other standalone statistics collection workstations.

Step 1 If the upgrade of the CWM server involves the upgrading of Solaris, check that the CWM databases and files have been exported and saved to a safe place and note the path to that safe place. Check also that, after saving the CWM data, the upgrade to Solaris 9 on the CWM server has been performed.

Step 2 On the Solaris 8 or Solaris 9 SCMSA workstation, log in as user root.

Step 3 Insert the Cisco Multiservice Center Stand Alone Statistics Collection Manager CD-ROM into the CDROM drive.

Step 4 Enter the following commands:
# cd /cdrom/cdrom0
# ls 
Step 5 Check for the script file statsdbunload.csh.

Step 6 Begin the execution of the script by entering the following command:
# ./statsdbunload.csh
This script saves the statsdb data in a newly created directory called statsdbupload that is located in /usr/users/svplus/tmp.

Step 7 If the statsdb is being preserved in multiple standalone machines all of which are connected to the same CWM server, rename the directories in the different machines so that each name is unique. Use the names statsdbunload, statsdbunload1, statsdbunload2, and so on.

Step 8 If upgrading from a Solaris 8 platform to Solaris 9, use the FTP facility to copy the directory to the same place that contains the exported databases from the CWM server machine.

The upgrade of the SCMSA workstation can now be performed.

Upgrading SCMSA

This section provides step-by-step procedures to upgrade your Statistics Collection Manager Stand Alone (SCMSA) server workstation.

To upgrade SCMSA without a disruption of the network management functions, the existing CWM system should be configured with multiple CWM gateways. The CWM gateways and the SCMSA stations are then upgraded one at a time thus preserving network management throughout the upgrade process. This process is described in detail later in this chapter.

Upgrading from a Solaris 8 Platform

The upgrade process for a SCMSA server from a Solaris 8 platform consists of the following five steps.

Step 1 If required, save the existing scmdb database, configuration files, and any other files that need to be preserved to an external safe place. For example, you may save these on a separate NFS mounted directory, a tape, or FTP'd to another machine.

Note This step must be performed first. (See Preserving scmdb Data section).

Step 2 If required, preserve the statsdb data. (See Preserving statsdb Data section).

Step 3 Install Solaris 9.

Step 4 Install any required Solaris 9 patches.

Step 5 Perform the SCMSA install procedure specifying the upgrade in the upgrade window.

Installing Solaris 9

This section is only for upgrades involving a move from Solaris 8 to Solaris 9.

When the SCMSA databases and other files have been saved, perform the following procedures described in Chapter 2.

1. Install Solaris 9.

2. Install Solaris 9 patches (refer to the most current release notes).

Note Make sure that the machine is rebooted at this point.

Upgrading the SCMSA Software

Installing the Standalone SCM software consist of responding to a series of windows. The windows can be regarded as being made up of three phases.

•Initial upgrade phase

•Configuring Informix partitions phase (either with or without meta devices)

•Completing the upgrade phase

Selecting the Installation Mode

To install the SCMSA software, perform the following steps:

Step 1 Log in to the SCMSA workstation as user root.

Note If the workstation is an Ultra 60 or other desktop system, merely log in from the keyboard.
If the workstation is a Netra 20 or other rackmount system, use another Sun workstation or PC as a console and log in remotely using telnet).

Step 2 Insert the Cisco SCMSA CD-ROM into the CD-ROM drive of the workstation.

Step 3 Enter the following commands:
# cd /cdrom/cdrom0
# ls 
Step 4 Check for the InstallSCMSA.sh file.

Step 5 Begin the install process by entering the following command:
# ./InstallSCMSA.sh
The following message is displayed.
Console Mode Option is recommended when you cannot connect to X Server 
 from current terminal (See if you can open an xterm to check!) 
 Do you Want to Launch Installer in Console Mode? (Yes / No): [No]:
Step 6 Respond No to continue the installation using the Installshield GUI.
Respond Yes to continue the installation using Console Mode Install.

Note Console Mode Install is a command line script procedure. It is an alternative to the GUI and is intended for users who do not have access to an X window device. Using Console Mode Install, the user can install SCMSA using an alpha-numeric terminal or a PC in terminal emulator mode.

Installshield GUI Installation

The installation classes are loaded (a process that takes several minutes).

The SCMSA Installation Welcome window appears.

Step 1 Click Next on the Welcome window to continue. The license agreement window appears.

Step 2 Click I Accept and then click Next. The Install Standalone Stats Collector or Standalone Statistics Manager window appears.

Step 3 Choose Standalone Stats Collector or Standalone Stats Manager as appropriate, and then click Next. At this point, the procedure differs slightly depending upon the user's selection.

Initial Upgrade Phase for SSC

The Upgrade window appears.

Step 1 Choose Yes and then click Next. The SCMSA version window appears.

Step 2 Choose the CWM version from which you are upgrading and click Next.

Step 3 If a Solaris 8 release is selected, the Solaris Version window appears. Otherwise, the procedure skips to Completing the Installation.

Step 4 Choose the version of Solaris from which the upgrade is being performed:

•If Solaris 9 is selected, click Next. Go to Step 5.

•If Solaris 8 is selected, you are prompted to enter the path to the databases. Enter the path of the import directory (the directory where the exported databases now reside) and click Next.

Step 5 When the appropriate upgrade information has been entered, the Upgrade Information confirmation dialog box appears. Check that the upgrade version is correct and click OK. If you attempt to upgrade from an invalid version, an error message appears.

Initial Upgrade Phase for SSM

The Upgrade window appears.

Step 1 Choose Yes and then click Next. The SCMSA version window appears.

Step 2 Select 15.3.00 and then click Next to proceed to Completing the Installation. *?*

Completing the Installation

If you are upgrading SSM, the CWM Server window appears. If you are upgrading SSC, this next window is skipped.

Step 1 Enter the name or IP address of the CWM server in which the SCM Control Server is located and click Next. The CORBA Communications Options window appears. It displays four choices for how the server identifies itself for CORBA (Orbix) communications:

•The CWM Server host name including a domain name

•The CWM Server host name without a domain name

•The IP address of the CWM server

•A user-specified address

Step 2 Select the method to use for your CWM network and click Next.

If you selected Host with DNS domain name, you are asked to specify the domain name.

If you selected Use specified IP Address, you are asked to specify the IP address.

Enter the Domain Name or IP Address as appropriate and click Next.

This domain name and IP address information allows the CWM clients access to the database. Also ensure that the workstation and the domain are reachable. You can enter the ping command to test this.

A confirmation screen appears before the actual installation of the files.

Step 3 If the information in the Confirmation window is correct, click Next. If it is not correct, click Back to the appropriate window and correct the wrong settings. When Next is clicked, the Installation Progress Window appears.

Step 4 After a short while, the User/Group message appears. Click Yes.

Step 5 If the CWM was installed previously, a message appears telling you that files already exist, and permission is requested to overwrite the files with new files.

Step 6 Click Yes to All. After a some time, an Install Log window appears. This log provides messages of events that occurred during installation. The SCMSA install log file is called scmsaexecinstall.Log and is located in the /usr/user/svplus/install directory.

A dialog box appears, informing you that the installation is complete.

Step 7 Click Finish. The software installation process is complete. The Install Shield window closes. The first time and only the first time that the SCMSA is installed, the system displays a message at this point stating that the kernel is changed.

Step 8 Click OK to reboot the system. The reboot sequence aligns the cylinders of your hard disks and shuts down the Solaris operating system. The OK prompt is displayed.

Step 9 Press the CD-ROM eject button on the CD-ROM drive to remove the CD-ROM.

Note After installing or upgrading SCMSA on a machine that has not previously had CWM installed, it is possible that an account in the name "svplus" has not been established. If this so, establish an svplus account manually.

Making Selections during Console Mode Upgrade

The Console Mode procedure consists of responding to a series of questions. The user is asked either to select an item from a list or to enter data (for example, a database path or a disk size).

Selecting an Item from a List.

When a list is displayed, each item in the list has an item number. Further, one item in the list is already selected as indicated by an X. For example:
Choose the Raw partition for Informix Physical Log:
[X]  1  -      /dev/rdsk/c1t0d0s7 ( 4000 MB)   
 [ ]  2  -      /dev/rdsk/c1t1d0s0 ( 2048 MB)  
 [ ]  3  -      /dev/rdsk/c1t1d0s1 ( 2048 MB)  
To select a choice enter its number, or 0 when you are finished [0]: 
The above example lists three disk partitions from which the user must select one. These items are numbered as 1, 2, and 3 and the first is already selected as indicated by [X].

The user can accept the already selected item or select another item by typing its number followed by the Enter key (in which case the list is displayed again but with the [X] against the selected item).

When the [X] is shown against the correct item (either in the initial display or after the user has selected another item), the user should press 0 followed by the Enter key. The following message is then displayed.
  Press 1 for Next panel, 2 for Previous panel, 3 to Cancel or 4 to
   Redisplay [1] 
The user then press 1, 2, 3, or 4 (as appropriate) followed by the Enter key. Normally this will be the 1 key to progress to next step in the upgrade process.

Entering Data

When requested enter the data and press the Enter key. If you want to change the entered data, press 1 and the Enter key and then start over. When the enter data are correct, press 0 and the Enter key.

Upgrading SCMSA Software from Solaris 8 to Solaris 9 with Multiple CWM Gateways

When upgrading from a network with multiple CWM gateways, a special sequence of steps needs to be followed. This procedure ensures that, at all times, there is one and only one master CWM in a CWM domain for a particular release and that the integrity of the network configuration and user data files is maintained. This procedure does involve some downtime in the SCMSA workstations.

Initial Conditions before Upgrade

Consider an example network that has two Release 15.0.00 or 15.1.50 CWM gateways running Solaris 8 consisting of one master and one secondary and two Release 15.0.00 or 15.1.50 Solaris 8 SCMSA workstations. All workstations are up and running, all are synced, and all need to be upgraded to their equivalent Solaris 9 versions.

Note Although this example uses a network with two CWM workstations and two SCMSA workstations, the same procedure can be extended to a network using any number of workstations.

The first CWM workstation to be started is automatically assigned the role of primary workstation. The second workstation to be started becomes a secondary workstation with priority 1. Subsequent workstations become secondary workstations with priorities of 2, 3, and so on. To ensure such a primary/secondary arrangement, the DomainGatewayList field in the CWMGateway.conf file for all CWM workstations must list all CWM gateways. Likewise, the DomainGatewayList field in the SCMGateway.conf file for all SCMSA workstations must list all the CWM gateways.

As shown in Figure 8-1, CWM A workstation is primary and CWM B workstation is secondary. The CWMGateway.conf field for all CWM gateways contains the following entry:
DomainGatewayList CWMA CWMB
SCMGateway.conf field for all SCMSA gateways contains the entry:
DomainGatewayList SCMSAA SCMSAB

Upgrade Procedure

The following steps upgrade the workstations, one by one, to Release 15.3.00.

Step 1 Stop the core process for all SCMSA workstations.

Note Statistics generated during the period when the SCMSA workstations are stopped are not lost. When the workstations are started again, statistics occurring during the down period are collected from the nodes.

Step 2 Stop the CWM core process for CWMA. This action causes CWMB to assume the role of primary.

Step 3 On CWMA perform the following steps.

a. Save the database.

b. Install Solaris 9.

c. Install HP OpenView.

d. Install CWM 15.3.00 (Solaris 9).

Use the Primary/Secondary select window to select CWM A as primary.

Step 4 Start the CWM core process for CWM A.

CWM A starts as primary but in a different gateway domain.

Step 5 The new state of the workstations is shown in Figure 8-2.

Step 6 Upgrade SCMSA A and SCMSA B to Solaris 9 as described earlier in this chapter.

Use the procedure described in the "Upgrading the SCMSA Software" section.

Step 7 Start the core process for both SCMSA A and SCMSA B.

The state of the workstations is now as shown in Figure 8-3.

Step 8 Stop the CWM core process for CWM B.

Step 9 On CWM B perform the following steps.

a. Save the database.

b. Install Solaris 9.

c. Install HP OpenView.

d. Install CWM 15.3.00 (Solaris 9).

Use the Primary/Secondary select window to select CWM A as primary and CWM B as secondary.

Step 10 Start the CWM core process for CWM B. CWM B starts as secondary in the same domain as CWM A.

The new state of the workstations is shown in Figure 8-4.

Figure 8-4 State of CWM Gateways after Step 7

CWM A 15.3.00, Sol 9
Core Running
Primary
DomainGateway List = A, B

CWM B 15.3.00, Sol 9
Core Running
Secondary
DomainGateway List = A, B

SCMSA A 15.3.00, Sol 9
Core Running

SCMSA B 15.3.00, Sol 9
Core Running
