164 Troubleshooting the Shared Storage Option
Common configuration issues with Shared Storage Option
Verify that the JNI HBA failover value was set to zero to avoid I/O hangs. This
value applies to bridges and HBAs.
Verify that the HBAs with the SCSI-3 protocols are compatible with the
operating system drivers.
Verify that your cluster configuration is supported.
For more information about cluster configuration, see the NetBackup Release
Notes
Verify that all of your Fibre Channel devices support your Fibre Channel
topology. For example, in a switched fabric topology, ensure that all devices
supported switched fabric.
Verify that Shared Storage Option is licensed on each server. To do so, select
Help > License keys from the NetBackup Administration Console on each
server. To enable Shared Storage Option, enter the Shared Storage Option
license key on each server.
Verify that you configured Shared Storage Option from the master server. You
must configure SSO from the master server not from a media server (or SAN
media server).
Verify that you configured the same robot control host on every host.
Remember that except for ACS and TLM robot types, only one host controls
the robot.
Verify that you used the Device Configuration Wizard rather than the
utility to configure Shared Storage Option. The wizard coordinates
configuration with all hosts that share the drives. The
create inconsistent configurations.
Verify that you selected the appropriate device hosts in the Device
Configuration Wizard , including the host with robotic control.
Fibre Channel connections to the drives and the robots cause increased
complexity in a NetBackup device configuration. On some operating systems,
SCSI-to-fibre bridges may result in inconsistencies in the device paths when
you restart a host. After a restart of the host, the device configuration should
be verified.
Verify that names across all systems that share the drives are consistent.
Test the drive paths on every media server.
Define NetBackup storage units for each media server. Do not select any
available media server in the storage units.
