This section explains upgrading cluster nodes.
Note
If you are using Host OS failover function in your environment, upgrade both host and guest OSes. You can upgrade either the host OS or the guest OSes first.
Before upgrading the host OS, stop the guest OSes.
When you upgrade PRIMECLUSTER to this version on the system where GDS netmirror volumes exist, at the first system startup after the upgrading, resynchronization copying of entire area of the netmirror volumes may be performed instead of just resynchronization copying of the volumes.
When upgrading in a system where /etc/modprobe.d/gds.conf file exists and "options sfdsksys sfdsksys_major = <major>" is specified, perform the following operation.
[pre-upgrade]
Delete the /etc/modprobe.d/gds.conf file.
Cancel the mirroring of the system disk.
[after-upgrade]
If the mirroring of the system disk has been canceled in the pre-upgrade operation, upgrade the cluster node and then set mirroring again.
