Preparing the second subcluster
Perform the following steps on the second subcluster before rebooting nodes in the first subcluster.
To prepare to upgrade the second subcluster

- Unmount all the VxFS file systems that VCS does not manage, for example:
# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 26G 3.3G 22G 14% / udev 1007M 352K 1006M 1% /dev tmpfs 4.0K 0 4.0K 0% /dev/vx /dev/vx/dsk/dg2/dg2vol1 3.0G 18M 2.8G 1% /mnt/dg2/dg2vol1 /dev/vx/dsk/dg2/dg2vol2 1.0G 18M 944M 2% /mnt/dg2/dg2vol2 /dev/vx/dsk/dg2/dg2vol3 10G 20M 9.4G 1% /mnt/dg2/dg2vol3 # umount /mnt/dg2/dg2vol1 # umount /mnt/dg2/dg2vol2 # umount /mnt/dg2/dg2vol3 - Make the configuration writable on the second subcluster.
# haconf -makerw
- On the nodes in the second subcluster, use the following command to take all the cache area offline:
# sfcache offline cachename
- Unfreeze the service groups.
# hagrp -unfreeze sg1 -persistent # hagrp -unfreeze sg2 -persistent # hagrp -unfreeze sg3 -persistent # hagrp -unfreeze sg4 -persistent
- Dump the configuration and make it read-only.
# haconf -dump -makero
- Take the service groups offline on node03 and node04.
# hagrp -offline sg1 -sys node03 # hagrp -offline sg1 -sys node04 # hagrp -offline sg2 -sys node03 # hagrp -offline sg2 -sys node04 # hagrp -offline sg3 -sys node03 # hagrp -offline sg4 -sys node04
- Verify the state of the service groups.
# hagrp -state #Group Attribute System Value SG1 State node01 |OFFLINE| SG1 State node02 |OFFLINE| SG1 State node03 |OFFLINE| SG1 State node04 |OFFLINE| SG2 State node01 |OFFLINE| SG2 State node02 |OFFLINE| SG2 State node03 |OFFLINE| SG2 State node04 |OFFLINE| SG3 State node01 |OFFLINE| SG3 State node02 |OFFLINE| SG3 State node03 |OFFLINE| SG3 State node04 |OFFLINE|
- Stop all VxVM volumes (for each disk group) that VCS does not manage.
- Stop VCS, I/O Fencing, GAB, and LLT on node03 and node04.
For systemd environments with supported Linux distributions:
# hastop -local # systemctl stop vxfen # systemctl stop gab # systemctl stop llt
For other supported Linux distributions:
# hastop -local # /etc/init.d/vxfen stop # /etc/init.d/gab stop # /etc/init.d/llt stop
- Make sure that the VXFEN, GAB, and LLT modules on node03 and node04 are not added.
For systemd environments with supported Linux distributions:
# /opt/VRTSvcs/vxfen/bin/vxfen status VXFEN module is not loaded # /opt/VRTSgab/gab status GAB module is not loaded # /opt/VRTSllt/llt status LLT module is not loaded
For other supported Linux distributions:
# /etc/init.d/vxfen status VXFEN module is not loaded # /etc/init.d/gab status GAB module is not loaded # /etc/init.d/llt status LLT module is not loaded
