Scsi Cables - HP Surestore Disk Array 12h - And FC60 Advanced User's Manual

SCSI Cables

Replacing SCSI cables requires that the disk enclosure be shut down. Shutting down the
enclosure will degrade the performance of the array during the replacement. When the
replacement is completed and the disk enclosure is powered up, the array will perform a
rebuild (since I/O has occurred to the array while the disk enclosure was powered off).
Array performance will be reduced until the rebuild is complete
To replace a SCSI cable, complete the following steps:
1. Open the disk enclosure front door.
2. Power the disk enclosure down by setting the power switch to off.
When replacing a SCSI cable, it must be disconnected from both the controller

enclosure and the BCC module. Disconnect the cable from the controller
enclosure first, then from the failed BCC. DO NOT disk connect the SCSI cable
from the BCC first or errors may occur when the enclosure is powered on.
3. Remove the SCSI cable from the controller enclosure connector.
4. Remove the SCSI cable from the BCC
5. Connect the SCSI cable to the BCC connector.
6. Connect the other end of the SCSI cable to the controller enclosure SCSI connector.
7. Disconnect all disk modules from the backplane connectors by releasing the locking
levers and pulling module out, about one inch. This step is required to ensure the disk
modules return to full operation when the enclosure is powered back up.
8. Power up the disk enclosure.
9. Reseat the disk modules one at a time:
a. Push the disk module in slot 0 into slot until it snaps into place.
b. Observe the Disk Fault LED, it should come on. When the Disk Fault LED goes out,
insert the next disk module.
c. Repeat the above steps until all disk modules are re-seated.
