Procedure
1.
When basic control path failover is enabled, the library is presented as LUN 0 on its own world-wide
node name.
2.
When basic control path failover is NOT enabled, the library is presented as LUN 1 on the drive world-
wide node name.
To verify basic control path failover, force a failover from the
Drives > Manual Control Path Failover
screen and then verify that the control path has moved to the passive drive.
• Navigate to the
Status > Partition Map > Configuration Status
screen.
• Verify that basic control path failover is enabled.
• Note the active and passive control path drives.
• Navigate to the
Drives > Manual Control Path Failover
screen.
• Click
Failover
.
• Click
Submit
.
• Navigate to the
Status > Partition Map > Configuration Status
screen.
• Verify that the active control path drive is the drive that was the passive control path drive in step 3.
Verifying advanced control path failover
To verify advanced control path failover, power off the control path drive to create a failover event. You
can find the active control path drive for a partition from the
Status > Partition Map > Configuration
Status
screen, shown in
Figure 6: Status of the Partitions Configuration to verify basic control path
on page 35 .
To cause a failover event, power off the active control path drive from the
Configuration > Drives >
Settings
screen and then verify that the partition still has access to the host.
Procedure
1.
Navigate to the
Status > Partition Map > Configuration Status
screen.
2.
Verify that advanced control path failover is enabled.
3.
Note the active and passive control path drives.
4.
Verify library connectivity.
5.
Navigate to the
Configuration > Drives > Settings
screen.
6.
For the active control path drive, deselect
Power On
.
7.
Click
Submit
.
8.
The active control path drive is powered off and the library control path switches to the passive control
path drive.
9.
Verify library connectivity.
