Follow the steps in this section if you are upgrading an HACWS configuration from PSSP 2.4, |PSSP 3.1.1, or PSSP 3.2 to PSSP |3.4.
Before following the instructions in this section, you should:
|An authentication method must be set in order for remote commands to |work properly. If your SP system contains nodes at PSSP |3.1.1 or earlier, the Kerberos V4 value must be set. For |SP systems containing nodes at PSSP 3.2 or later, any value is valid |(Kerberos V5, Kerberos V4, or Standard AIX).
|If the value is not set, use the chauthent command to |enable k4. Issue:
chauthent -k4 -std
|Perform this step for both control workstations.
The suggested network tunable values for your control workstations are as follows:
sb_max 163840 ipforwarding 1 tcp_sendspace 65536 tcp_recvspace 65536 udp_sendspace 32768 udp_recvspace 65536 tcp_mssdflt 1448 tcp_pmtu_discover 0 udp_pmtu_discover 0
Verify that the network tunable values on both control workstations are correct. Use the no command to display these values. To display all of the network tunable values at once, issue the command:
/usr/sbin/no -a
To change the value of the thewall network tunable to 16384, issue the command:
/usr/sbin/no -o thewall=16384
When you change a network tunable value, the change takes effect immediately. However, the change is not preserved across a reboot. To make the change permanent, add the required no command to the bottom of the /etc/rc.net script. Refer to the no command man page for more information about changing network tunable values.
Follow the instructions in Step 7: Review space requirements for NIM boot images.
Follow the instructions in Step 9: Review space requirements for /spdata.
Follow the instructions in Step 10: Create the required /spdata directories.
Follow the instructions in Step 11: Copy the AIX 4.3.3 LP images and other required AIX LPs and PTFs.
For both control workstations, follow the instructions in Step 12: Install correct level of PAIDE on the control workstation.
Follow the instructions in Step 13: Copy the PSSP images for PSSP 3.4.
|Follow the instructions in Step 14: Install the runtime prerequisites. Perform this step for both control |workstations.
Follow the instructions in Step 15: Install (copy) the basic AIX (mksysb) image.
If you have not already done so, make sure that HACMP is running on both control workstations and the primary control workstation is the active control workstation, or the one that is providing the control workstation services.
While HACMP is still running, you need to stop the control workstation applications on both control workstations. While the primary control workstation is the active control workstation, the backup control workstation will act as a client of the primary control workstation. You need to turn this off by issuing the following command on the backup control workstation:
/usr/sbin/hacws/spcw_apps -d
Next, you need to stop control workstation services on the primary control workstation by issuing the same command on the primary control workstation.
You need to install the |PSSP 3.4 file sets on both control workstations. When the PSSP file sets are installed, files are copied into the /spdata/sys1 directory. This requires special consideration for an HACWS configuration, because both control workstations share the same /spdata file system, which resides in a shared volume group. At this point, the /spdata file system should be mounted on the primary control workstation, so files copied to the /spdata/sys1 directory on the primary control workstation get written to the shared /spdata file system, and files copied to the /spdata/sys1 directory on the backup control workstation get written to the backup control workstation's / (or root) file system. Since both control workstations share the same /spdata file system, the files that are copied to the backup control workstation are not needed, and they will get removed later by the install_hacws command in Step 16: Complete PSSP installation on both control workstations. In the meantime, you need to make sure there is at least 4 MB of free space in the / (or root) file system on the backup control workstation, or installation on the backup control workstation may fail.
You can install the |PSSP 3.4 file sets on the primary control workstation from either the |/spdata/sys1/install/pssplpp/PSSP-3.4 directory, which is in the locally mounted /spdata file system, or you can install directly from the installation media. However, IBM suggests that you install the |PSSP 3.4 file sets on the backup control workstation directly from the installation media. You should not mount the /spdata file system on the backup control workstation to install PSSP. Now you may proceed to install the |PSSP 3.4 file sets on both control workstations. Remember that you must also install the |ssp.hacws 3.4.0.0 file set on both control workstations. You can perform file set installation from the command line by issuing the installp command, or you can use SMIT by issuing the smit install_latest command. Refer to the AIX Installation Guide for more details on how to use these commands.
|To get the Kerberos V4 administrative principal, follow the instructions in |Step 17: Obtain credentials.
|If your starting PSSP level is earlier than PSSP 3.2, the |authentication method for SP Trusted Services may not have been set. To |determine if the authentication method was previously set, issue the |lsauthts command. |If the response is compat, you can skip this |step. If the authentication method for SP Trusted Services is not set to |compat and you are migrating from a version of PSSP earlier than PSSP |3.2, issue the chauthts command. Issue:
chauthts compat
|Run the install_hacws command. The
|install_hacws command runs SDR_init which logs information
|in /var/adm/SPlogs/SDR/SDR_config.log.
| If using: | Do this: |
|---|---|
| SMIT |
|
| install_hacws | Enter:
/usr/sbin/hacws/install_hacws -p primary_hostname -b backup_hostname -s |
|Follow the instructions in Step 21: Verify the authentication values in the SDR.
Run the hacws_verify command.
| If using: | Do this: |
|---|---|
| SMIT |
|
| hacws_verify | Enter:
/usr/sbin/hacws/hacws_verify |
Follow the instructions in Step 22: Run SDR and System Monitor verification test.
Follow the instructions in Step 23: Configure PSSP services and set up the site environment.
Follow the instructions in Step 24: Update the state of the supervisor microcode.
Start control workstation services on the primary control workstation by issuing the following command:
/usr/sbin/hacws/spcw_apps -u
After this command completes on the primary control workstation, get the backup control workstation to synchronize with the primary control workstation by issuing the same command on the backup control workstation.
|In order to monitor any new PSSP 3.4 hardware and to utilize |the latest configuration database for Perspectives, you should perform the |following steps at this time:
|Issue /usr/sbin/rsct/bin/haemctrl -k on the control workstation |and on each of the nodes in the system partition. For PSSP 2.4 |or earlier, issue /usr/lpp/ssp/bin/haemctrl -k on the control |workstation and on each of the nodes in the system partition.
|You can use the dsh or Sysctl commands to run the command |on multiple nodes from the control workstation. For more information on |using these commands, see the "Parallel Management commands" chapter |in PSSP: Administration Guide.
|On the control workstation, issue the lssrc -s |haem.domain_name command. On the nodes, issue the |lssrc -s haem command.
|You can use the dsh or Sysctl commands to run the command |on multiple nodes from the control workstation. For more information on |using these commands, see the "Parallel Management commands" chapter |in the PSSP: Administration Guide.
|The status of each daemon should indicate that it is inactive.
|Issue /usr/sbin/rsct/bin/haemctrl -s on the control workstation |and on each of the nodes in the system partition. For PSSP 2.4 |or earlier, issue /usr/lpp/ssp/bin/haemctrl -s on the control |workstation and on each of the nodes in the system partition.
|You can use the dsh or Sysctl commands to run the command |on multiple nodes from the control workstation. For more information on |using these commands, see the "Parallel Management commands" chapter |in PSSP: Administration Guide.
Follow the instructions in Step Step 26: Refresh the pmand daemons (PSSP 2.4 only).
Follow the instructions in Step 28: Run verification tests.
|Follow the instructions in Step 30: Validate the network adapters.
Your migration to |PSSP 3.4 is now complete. You should test your HACWS configuration by performing a control workstation failover from the primary control workstation to the backup control workstation, and then failover from the backup control workstation back to the primary control workstation. Perform additional failover testing as needed. Refer to Step 31: Validate the control workstation for additional instructions.
At this point, refer back to High-level migration steps to determine the next step in your SP system migration process.
