Start of validation for all HAFO configured devices.

=====================================================

VALIDATING ** Ldev: 50 Pri path: 8.15.0 Alt path: 48

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ldev 50 configuration Validated Successfully

VALIDATING ** Ldev: 51 Pri path: 8.15.1 Alt path: 48

Ldev 51 configuration Validated Successfully

End of validation for all HAFO configured devices.

===================================================

Using the

DOHA

command checks each HAFO configured Ldev in the following

ways:

1. The configured Ldev and primary path are compared against internal system

I/O tables. This confirms that the Ldev and paths exist.

2. The alternate path is confirmed against internal system I/O tables. This

confirms that the path existed at boot time.

3. Using the primary path, the Ldev volume label is read. This confirms that

the primary path is working and does, in fact, connect to the appropriate

Ldev.

4. The device manager connects to the alternate path. This confirms it exists.

5. Using the alternate path, the Ldev volume label is read. This confirms that

the alternate path is working and does connect to an Ldev.

6. Ldev volume labels are compared. This confirms that the two paths can

access the same Ldev.

A full six-step validation is always performed in the following situations:

• On system boot

• Executing the

DOHA

command

• By each device manager during a failover event
