1

Attempt to open an Subsystem Management Window for the remote storage subsystem by highlighting the remote storage subsystem in the Enterprise Management Window and selecting the Tools>>Manage Device menu option.

If...

Then...

The Subsystem Management Window can connect to the storage subsystem

Select the Recovery Guru button on the Subsystem Management Window of the remote storage subsystem.

If...

Then...

There are failures detected on the remote storage subsystem

Correct all failures listed in the Recovery Guru Summary area by selecting the failure and performing the displayed recovery procedure.

Go to Step 4.

There are no failures detected on the remote storage subsystem

Go to Step 2.

The Subsystem Management Window cannot connect to the storage subsystem

Check to see that the remote storage subsystem's power supplies are properly connected to an operating power source and has the power switch in the on position.

If...

Then...

You find a power or power supply problem

Correct the problem and go to Step 4.
