Page 137 highlights

In the Logical Disk Server Presentation dialog box, it shows "Unknown Server." What does this mean? Symptoms: An Unknown Server may appear if: • The logical disk in the storage subsystem is assigned to an HBA, but the application cannot discover that HBA in any of the servers. • The server is offline. • The HBA is from a vendor other than HP. • You made specific changes to an HBA (for example, changing the type). In the Logical Disk Server Presentation dialog box, you may then be unable to deny access to that HBA or server (that is, you cannot remove it from the "allowed" list). This behavior occurs because the removed HBA remains saved by the array. To permanently remove this type of HBA, you must use an array utility: • For EVA storage, use EVA Command View. • For MSA storage, use ACU (Array Configuration Utility). To access the array utility, view either the Physical Connection map or LUN assignment map, right-click a storage subsystem icon, and on the shortcut menu, click Launch Subsystem Management Application. Solution: Ensure that the server is online and that the HBA is from HP and not from another vendor. To permanently remove the HBA, use an array utility as described in the previous paragraph.

The HBA is from a vendor other than HP.
You made specific changes to an HBA (for example, changing the type).
In the Logical Disk Server Presentation dialog box, you may then be unable to deny
