Checking Path Failover; Automatic Mounting Example Explanation - HP StorageWorks XP10000 - Disk Array Configuration Manual

1. After first making a backup copy of the file, edit the /etc/fstab file. Add a line for each new
device to be mounted.
Example
#vi /etc/fstab
/dev/disk/dsk4a / ufs rw 1 1
/proc /proc procfs rw 0 0
/dev/disk/dsk12a /usr ufs rw 1 2
/dev/disk/dsk12b swap1 ufs rw 0 2
/dev/disk/dsk15c /HP5700_LU2c ufs rw 1 3

/dev/disk/dsk12b
/dev/disk/dsk15a
Notes: For UFS systems, you must File System Check (fsck) disks that contain mount points before
mounting other disks on those mount points.
2. Shut down and reboot the system.
3.
Use the df or df –k command to verify file system auto mounting.

Checking path failover

The disk array supports Tru64 path failover (Tru64 v5.1B–2 and later only). You can connect multiple
FCAs to the disk array with shared LUNs. Confirm the existence of multiple paths for devices as follows:
1. Type hwmgr -view device to obtain the HWID for the device.
2. Type hwmgr -show scsi -full -id HWID to confirm the status of paths to the device.
If more than one path is currently connected, the status of each path shows as Valid. If you
change the cabling configuration, the old paths will show as Stale. Use the hwmgr -refresh
scsi command to remove the stale paths.
CAUTION:
Tru64 5.1B and later fully support dynamic load balancing and failover when multiple FCAs
are connected to the same LUN. This feature is ONLY available with version 5.1B and later.
