Adding Disk Enclosures to Increase Capacity

AUTION
The disk array components must be powered up in the specified sequence -
disk enclosures first, followed by the controller enclosure. Failure to follow the
proper sequence may result in the host not recognizing LUNs on the disk
array.
1. Ensure all power cables are connected to the controller enclosure and disk enclosures.
2. Power up the disk array in the following sequence:
a. Power up all the disk enclosures. Wait approximately two minutes for all disk
enclosure activity to complete.
b. Power up the controller enclosure.
c. Wait for five minutes. During this period the array will discover the new
configuration. It is important that the array be allowed complete the discovery
process.
3. Check for any disk faults. If a disk fault occurs, remove the disk, wait for at least 15
seconds, then reinsert the disk. The disk array controller should clear the fault on the
disk once it has spun up.
Note
If the disk fault will not clear, it may be necessary to replace the disk. If a new
disk does not clear the fault, contact HP Support.
4. Add any new disks to the disk enclosures. Refer to your expanded configuration
drawing for information on what slots to install the disks in.
Note
If you are adding disks that were installed in another Disk Array FC60, make
sure the disks have a status of Unassigned before installing them. If the disks
are marked as part of a LUN from the original array, the disk array will try to
recreate the LUN.
5. Connect the Fibre Channel cable(s) from the host to the controller enclosure. Refer to
the label on the cable to ensure the proper connection is maintained. Care should be
