Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

Note the following limitations for issuing CVM commands from the slave node:
■ The CVM protocol version 100 or later is required on all nodes in the cluster.
See “Displaying the cluster protocol version” on page 459.
■ CVM uses the values in the defaults file on the master node when CVM executes
the command. To avoid any ambiguity, we recommend that you use the same
values in the defaults file for each of the nodes in the cluster.
■ CVM does not support executing all commands on the slave node. You must
issue the following commands only on the master node:
■ Commands that specify a controller name. For example:
# vxassist -g shareddg make sharedvol 20M ctlr:fscsi0
■ Commands that specify both a shared disk group and a private disk group.
For example:
# vxdg destroy privatedg shareddg
■ Commands that include the defaults file as an argument. For example:
# vxassist -d defaults_file
■ Veritas Volume Replicator (VVR) commands including vxibc, vxrlink,
vxrsync, vxrvg, vrport, vrstat, and vradmin.
■ The vxdisk command options that act on shared disk groups.
See “CVM commands supported for executing on the slave node” on page 536.
