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 only). You can connect
multiple HBAs 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 command to remove the stale paths.
Caution: Tru64 version 5 fully supports dynamic load balancing and failover
when multiple HBAs are connected to the same LUN. This feature is ONLY
available with version 5.
On Tru64 version 4, DO NOT connect multiple HBAs to the same LUN and
DO NOT allow the same LUN to be accessible from multiple HBAs on Tru64
version 4 hosts. ON the version 4 system, this will allow multiple device names
to access the same LUN. If both device names are used, data corruption will
result.
