Chapter 1: Matrix Server Commands 29

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
