Configuring basic control path failover, Enabling control path port failover on the library – HP StoreEver MSL6480 Tape Library User Manual

Figure 11 Standby and active ports
After verifying that the configuration change was successful, verify that the hosts with access to the
tape drive are still able to communicate with the drive.
After verifying host access via the initial path, force a data path port failover by disconnecting the
cable from the active port on the drive or using an FC switch management interface to down the
port connected to the tape drive.
The drive status display shows which drive port is active and which port is in standby. After
disconnecting the cable from the active port verify that the library network management page port
status shows that the active port has changed. Reconnect the disconnected port and verify that it
shows as Standby. Verify that each host still has access to the tape drive.
If a particular port is the preferred active port and it is configured as Standby you can force selection
of a particular port as the active port by disconnecting the cable from the other port.
Configuring basic control path failover
Enabling control path port failover on the library
The HP StoreEver MSL Tape Libraries only support basic control path failover when used in a Fibre
Channel SAN and connected as fabric devices. The minimum configuration is:
•
A library or partition within a library with two LTO-5 or two LTO-6 Fibre Channel drives of the
same type (Ultrium 6250 half height; 3000 half height or Ultrium 3280 full height)
•
All drive ports configured to use a “Fabric N/F” connection
The default port configuration for HP StoreEver MSL Tape Libraries is Automatic and must be
changed.
shows the HP StoreEver MSL Tape Library network administration
drive configuration pane for a dual-port drive. The configuration for port A is set correctly for use
with basic control path failover. The configuration for port B is still set to the default setting of
“Automatic”. A single-port drive will not have port B.
