Configuration requirements after enabling control path failure
When basic control path failover is enabled, the library is no longer presented as a logical unit
behind the tape drive and is assigned a new Fibre Channel node name.
Verifying basic control path failover
After enabling basic control path failover, verify the configuration of both paths. To verify both
paths, first verify that the hosts configured for access to the library are able to communicate with
the library. The library Worldwide Node Name might need to be added to switch zones before
the library is accessible. After the host access has been verified use the library front panel or the
library management interface to power off the drive marked as hosting the library logical unit
number Drive 1 (LUN) in
- Configure: Drives.
After the library has powered off the drive hosting the library control path, the LUN indicator should
move to the alternate control path drive. When the library has reported that the drive has been
successfully powered off and the LUN indicator has moved to the alternate control path drive,
verify that host connectivity to the library has not changed. It may be necessary to configure switch
zoning to allow host access.
After verifying library connectivity using each of the library control paths the library control path
may be moved back to the original drive if so desired by using the Alternate Drive for Library
Control Path option (see
).
