mxsancheck – check server’s SAN access

Synopsis

/opt/polyserve/bin/mxsancheck

Description

The mxsancheck command determines whether a server has SAN access and is ready to mount filesystems. The command is intended to be used in scripts and returns 0 on success and 1 on failure.

mxsanconf – configure FC switches

Synopsis

/opt/polyserve/sbin/mxsanconf <FC-switch ...>

Description

When a matrix is configured to use fabric-based fencing, mxconfig runs the mxsanconf command on each node to configure the list of FibreChannel switches that will be managed by Matrix Server. The command creates or updates the files /etc/opt/polyserve/psSAN.cfg and /var/opt/polyserve/FCswitches.

<FC-switch>is either the name or IP address of a switch to be managed. All switches to be configured must be specified in the same command. The node must be unfenced when the command is run. If the <FC-switch> parameter is not specified, the command uses the FC switches listed in /var/opt/polyserve/FCswitches (if that file exists).

In general, this command should not be run directly.

mxsanlk – show SAN ownership locks

Synopsis

/opt/polyserve/tools/mxsanlk

Description

Matrix Server uses a set of disk-based data structures called SANlocks to protect filesystem integrity. If a problem causes a matrix to split into two or more network partitions, the SANlocks ensure that only one of the resulting network partitions has access to the SAN. Each SANlock is stored in a
