HP StorageWorks 1000 Modular Smart Array maintenance and service guide (257547-003, October 2006)

4. Attach SCSI cables to the MSA expansion SCSI connectors.

5. Attach the SCSI cables to the expansion storage enclosures.

6. Attach the power cords to the power supplies at the rear of the enclosures.

7. Power on each enclosure and wait for it to complete its startup routine.

8. Power on the MSA array controller system using the power button on the front of the system.

9. Wait for the MSA to complete its startup routine.

10. Power on the host servers and allow them to boot.

11. Run the ACU or the MSA-CLI to verify that the current conﬁguration is maintained and new volumes

are identiﬁed. If the migrated volumes are not identiﬁed, power down the system and verify the

connections.

12. Run the ACU or the MSA-CLI to add LUNs. Some systems may require rebooting to use the new LUNs.

permanent loss of data. Before moving hard drives and arrays, run the ACU or the MSA-CLI.

Before moving hard drives, the following conditions must be met:

• No hard drives are failed, missing, or degraded.

• No more than 32 LUNs will be conﬁgured for a controller.

• The array should be in its original conﬁguration with no active spare hard drives.

• Capacity expansion is not running.

• Controller ﬁrmware is the latest version (recommended).

Before moving an array from one controller to another, the following additional conditions must be met:

• All hard drives in the array must be moved at the same time.

• Positions of hard drives on the destination controller must remain the same during relocation of

the array.

When the appropriate conditions are met, perform the following procedure to move the hard drives:

1. PowerOfftheMSAstoragesystemasdetailedinRemoving power from the MSA.

2. Move the hard drives.

3. Power On the MSA storage system as detailed in Applying power to the MSA.

4. The following message should be displayed on the LCD front panel of the controller 86 DRIVE

POSITION CHANGE DETECTED.

IMPORTANT:

If the following LCD message is displayed: 121 NO VOLUMES DETECTED,turnOff

system immediately to avoid data loss, and return the hard drives to their original locations.

5. Check the new conﬁguration by running the ACU or MSA-CLI.
