Parameter Description

Enter Config Mode

Click to place the HA Cluster in a state that allows the Primary MDC to restart CVFS and individual FSMs without incurring an HA Reset, failover of any file systems, or transfer of Primary status to the peer MDC.

Note: This is required for making configuration changes to the HaShared file system using the GUI.

Caution: When exiting HA Config mode, StorNext is stopped, which also fuser any processes which have files open on the file system from either node. Prepare your systems before entering HA Config mode.

Exit Config Mode

Caution: Setting haFsType to HaUnmonitored disables the HA monitor timers used to guarantee against split brain. When two MDCs are configured to run as an HA pair but full HA protection is disabled in this way, it is possible in rare situations for file system metadata to become corrupt if there are lengthy delays or excessive loads in the LAN and SAN networks that prevent an active FSM from maintaining its branding of the ARB in a timely manner.
