HP StoreVirtual 4630 Storage Maintenance Guide (AX696-96343, December 2013)

The following HP 4630 system components are hot-pluggable; therefore, you do not need to power
down the device before replacing a part:
• D2700 disk drives
• External fans
• Power supplies
• Storage blade disk drives
All other HP 4630 system components are not hot-pluggable. You must first power down the device
before replacing a part.
CAUTION: To prevent losing access to data during any maintenance operation on components
of the SAS fabric, including the SAS switches, SAS cables, and I/O modules on the disk enclosure,
first power down the storage blades using the procedures to shut down the management group in
the HP StoreVirtual Storage Online Help or the HP StoreVirtual Storage User Guide.
Replacing the storage blade and storage blade components
There are two ways that the storage blade can be replaced:
• Replace the storage blade by moving all working components (drives, controllers, FlexLOM)
from the original storage blade to the new storage blade.
• The original storage blade is not bootable and you receive a new storage blade with new
physical drives. You must image the new storage blade and initiate the OS recovery procedure
using the TUI.
For more detailed instructions on replacing the storage blade or storage blade components, see
Table 4 (page 20) for resources.
To initiate OS recovery:
1. Connect to the storage blade using iLO or the USB dongle connected to the storage blade.
On the console, enter start at the prompt and then log in.
2. Select Support Operations.
3. Select Initiate OS Recovery. On the screen that displays, select OK to confirm the recovery
operation.
After the restore operation completes, the storage system restarts.
Replacing a storage blade
This section describes the implications for the HP 4630 system software and not the mechanical
aspects of replacing the storage blade.
If possible, you should verify the firmware version of a replacement storage blade before inserting
it in the blade enclosure:
• If an empty bay is available:
1. Install the replacement blade in the empty bay.
2. Update the firmware on all components.
3. Install the replacement blade in the bay where the failed blade was installed.
• If an empty bay is unavailable:
1. Power down the failed blade.
2. Using SAS Virtual Manager, disassociate the zone from the blade bay.
3. Install the replacement blade in the bay and update the firmware on all components.
4. Power down the storage blade.
5. Using SAS Virtual Manager, associate the zone with the blade bay.
