14. Verify the SAN configuration
This step verifies that the SAN devices are configured appropriately and can be
viewed from the servers that will be in the cluster. You will need to perform this step
on each server.
If an HBA driver has not already been loaded, run the following command to load
the driver:
# /etc/init.d/pmxs load
Next, run the following command to see a list of devices.
# cat /proc/partitions
Review the output to verify that the SAN is configured as you expect.
For installations using fabric-based fencing, verify that HP Scalable NAS can
communicate properly with each switch. Run the following command, which displays
the nameservice entries of connected and loaded HBA and Storage ports.
# /opt/hpcfs/sbin/PSANinfo -c <community string> <FC switch
IP address>
If the command fails, you will need to resolve the problem before proceeding with
the installation.
HP Scalable NAS and the FC switches must use the same community string. You can
set the community string for HP Scalable NAS when you configure the cluster later
in this procedure.
15. Verify the patched kernel for FS Option for Linux
This step applies to sites that will be using FS Option for Linux.
Verify that the FS Option for Linux patches have been correctly applied to the kernel.
Run the following command to determine whether the nfsd kernel module is loaded:
lsmod | grep nfsd
If the module is not loaded, start the NFS services. For RHEL5, run the
/etc/init.d/nfs start command. For SLES10, run the
/etc/init.d/nfsserver start command.
Next, run the exportfssync -t command to determine whether the FS Option
kernel patches have been applied correctly. The command should report the following:
