Comments

Checked for:

existence

availability on each node

same physical volumes on each node

physical volumes connected on each node

Checked only on nodes configured to run the package.

Checked for modular packages only, as part of package validation (cmcheckconf -P)

Standby status is checked for each single NIC; cmviewcl also reports APA status.

cmviewcl

flags offline standby in an existing cluster, but not for a cluster that is being created.

Quorum Server (cluster)

cmcheckconf (1m), cmapplyconf

Commands check that the quorum

through both the IP addresses.
