Installing and Configuring the HBA Driver

10. Execute the following commands from a command window:

	powermt restore
	powermt display
	At this point, two HBA’s should be present in the display and the
	FC HBA’s should be duplexed in the ftSMC. It may be necessary
	to repeat steps 9 and 10.
EMC Symmetrix
	Use of this procedure requires SYMCLI installed on the host system.
Arrays with Device	Alternatively, EMC ControlCenter can be used to perform the HBA
Masking Enabled1	replacement.

1.Using SYMCLI, run symmask list logins to view the old WWN/iSCSI HBAs.

2.Remove all cables to the IO slice with the defective HBA, and remove the IO slice.

3.Replace the defective QLogic HBA with the new HBA of same Stratus part number (that is, U525 or U526). The HBA should be inserted into same PCI slot from which the defective HBA was removed. (Inserting the replacement HBA into another PCI slot requires a driver to be loaded for the HBA)

4.Re-insert the IO slice with the new HBA, and re-connect all cables.

5.Let the IO Slice come on-line and duplex, as shown in the Stratus ftServer Management tool.

6.Change the FC switch zoning to add the WWN of the replaced HBA to the appropriate zones.

7.Run symmask list hba or discover to view the new initiator (for example, WWN).

8.Run symmask replace to substitute a new WWN for all occurrences in the database of the old WWN.

9.Run symmask discover to establish the new names in the history table, or run symmask rename to assign a WWN to the new HBA in both the database and the history table.

1.Symmetrix Arrays without device masking enabled do not require this procedure; Symmetrix Arrays with device masking enabled only require replacing the HBA WWN used in switch zoning.
