VERITAS CLUSTER SERVER (VCS) UPGRADE MAINTENANCE PROCEDURE
Here's a procedure to upgrade VCS or shutdown VCS duringhardware maintenance.
1. Open, freeze each Service Group, and close the VCS config.
haconf -makerw hagrp -freeze -persistent haconf -dump makero
2. Shutdown VCS but keep services up.
hastop -all -force
3. Confirm VCS has shut down on each system.
gabconfig -a
4. Confirm GAB is not running on any disks.
gabdisk -l(use this if upgrading from VCS 1.1.x)
gabdiskhb -l gabdiskx -l
If it is, remove it from the disks on each system.
gabdisk -d(use this if upgrading from VCS 1.1.x)
gabdiskhb -d gabdiskx -d
5. Shutdown GAB and confirm it's down on each system.
gabconfig -U gabconfig -a
6. Identify the GAB kernel module number and unload it from each system.
modinfo | grep gab modunload -i
7. Shutdown LLT. On each system, type:
lltconfig -U
Enter "y" if any questions are asked.
8. Identify the LLT kernel module number and unload it from each system.
modinfo | grep llt modunload -i
9. Rename VCS startup and stop scripts on each system.
cd /etc/rc2.d mv S70llt s70llt mv S92gab s92gab cd /etc/rc3.d mv S99vcs s99vcs cd /etc/rc0.d mv K10vcs k10vcs
10. Make a backup copy of /etc/VRTSvcs/conf/config/main.cf. Make a backup copy of /etc/VRTSvcs/conf/config/types.cf.
Starting with VCS 1.3.0, preonline and other trigger scripts must be in /opt/VRTSvcs/bin/triggers. Also, all preonline scripts in previous versions (such as VCS 1.1.2) must now be combined in one preonline script.
11. Remove old VCS packages.
pkgrm VRTScsga VRTSvcs VRTSgab VRTSllt VRTSperl VRTSvcswz
If you are upgrading from 1.0.1 or 1.0.2, you must also remove the package VRTSsnmp, and any packages containing a .2 extension, such as VRTScsga.2, VRTSvcs.2, etc.
Also remove any agent packages such as VRTSvcsix (Informix), VRTSvcsnb (NetBackup), VRTSvcssor (Oracle), and VRTSvcssy (Sybase).
Install new VCS packages.
Restore your main.cf and types.cf files.
12. Start LLT, GAB and VCS.
cd /etc/rc2.d mv s70llt S70llt mv s92gab S92gab cd /etc/rc3.d mv s99vcs S99vcs cd /etc/rc0.d mv k10vcs K10vcs
/etc/rc2.d/S70llt start /etc/rc2.d/S92gab /etc/rc3.d/S99vcs start
13. Check on status of VCS.
hastatus hastatus -sum
14. Unfreeze all Service Groups.
haconf -makerw hagrp -unfreeze -persistent haconf -dump -makero
