Notes: For U FS systems, you must File System Check (fsck) disks that contain mount points before
mounting other disks on those mount points.
2. Shut d own 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
HBAs to the dis
karraywithsharedLUNs.Confirm the existence of mu ltiple 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 con firm the status of paths to the device.
If more than one path is currently connected, the status of each path shows as Valid.Ifyouchange
the cabling configuration, the old paths will show as Stale.Usethehwmgr -refresh command
to remove the stale paths.
CAUTION:
Tru64 version 5.1B and later fully support dynamic load balancing and failover when
multipleHBAsareconnectedtothesameLUN.ThisfeatureisONLYavailablewithversion
5.1B and la
ter.
