Installation and Reference Guide HP StorageWorks Secure Path 3.0F Service Pack 4 for HP-UX 11i v1.0 and 11i v2.0 (5697-8001, March 2009)

8. If the array is in SCSI-2 mode and you want to use the SCSI-3 mode, verify that unit D0 is unas-
signed. If it is assigned, delete D0 and reassign. To do this, enter the following command:
HSG80> delete D0
Go to step 12.
9. If the array is not in SCSI-2 mode, set the array to SCSI-2 mode by entering the following com-
mand:
HSG80> set this_controller scsi_version=scsi-2
10. Restart the controllers to have SCSI-2 take effect by entering the following command:
HSG80> restart other_controller
HSG80> restart this_controller
Wait for two minutes for the controllers to reboot before proceeding.
11. Verify that the controllers are now in SCSI-2 mode by entering the following command:
HSG80> show this_controller
12. Perform the following steps if this is a new factory-configured array or one that is being recon-
figured. The array's internal connection table may contain connections that are out of date.
a. Review the array's internal connection table by entering the following command:
HSG80> show connections
b. Delete all connections to this host that are shown in the array's internal connection table.
The first time the server scans the Fibre Channel bus during boot, the new connections are
registered.
c. Delete each connection by entering the following command:
HSG80> delete connection_name
Connection_name is one of the names listed in the array's internal connection table, which
is displayed when you ran the show connections command in step a.
13. Complete the array setup by creating LUNs and assigning LUN unit numbers. To do this, note
the following information:
• Refer to the HSG80 ACS Solution Software for HP-UX installation and configuration guide
that came with your StorageWorks Solution Software Kit for details.
• If you are reconfiguring an array set up for SCSI-2 that already has LUNs configured, you
may use these units without reconfiguring as long as you are using units D0 through D7.
However, if you are using offset LUNs D8 through D199, you must reconfigure these units.
• In a SCSI-3 array, you can use units D1 through D127. Units D128 through D199 must be
reconfigured.
14. Follow the procedures described in Configuring optional HSG80-based array features, as needed.
When you have completed any optional array feature, follow the procedure described in System
configuration, to configure the system for Secure Path.
Configuring optional HSG80-based array features
This section provides the following optional HSG80-based array feature setup information and
procedures, including:
• Setting up additional SCSI-2 LUNs
• Setting a preferred unit to a controller
• Using SCSI-3
• Managing the command console LUN in SCSI-2 mode
