mxsanconf – configure FC switches
Synopsis
/opt/hpcfs/sbin/mxsanconf <FC-switch ...>
Description
When a cluster is configured to use fabric-based fencing, mxconfig runs the
mxsanconf command on each node to configure the list of Fibre Channel switches
that will be managed by HP Scalable NAS. The command creates or updates the
files /etc/opt/hpcfs/psSAN.cfg and /var/opt/hpcfs/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/hpcfs/
FCswitches (if that file exists).
In general, this command should not be run directly. If you need to reconfigure FC
switches, run mxconfig instead, and change the information on the switch
configuration dialog. For more information, see the HP Scalable NAS File Serving
Software installation guide.
mxsanlk – show SAN ownership locks
Synopsis
/opt/hpcfs/tools/mxsanlk
Description
HP Scalable NAS uses a set of disk-based data structures called SANlocks to protect
filesystem integrity. If a problem causes a cluster 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 membership partition. Before a
cluster can begin accessing the SAN, it must first acquire a majority of the SANlocks.
The SANlocks are acquired in order.
mxsanlk displays the status of the SANlock stored in each membership partition. It
can be used to determine whether any of the membership partitions need to be
repaired. Also, if a network partition occurs, mxsanlk can be used to determine
which network partition has control of the SAN.
