Figure 6 HP Smart Array P721m controller
1. Cache module
2. Capacitor pack cable connector
To replace the P721m controller:
NOTE:
For detailed instructions, see "Installing a mezzanine controller in a previously configured
server blade" in the HP Smart Array Controllers for HP ProLiant Servers User Guide. For detailed
instructions on replacing the cache module and capacitor, see "Upgrade and replacement
procedures" in the HP Smart Array Controllers for HP ProLiant Servers User Guide.
1.
Verify component failure by checking the following:
Failure to detect physical drives and logical drives or the P721m RAID BIOS posted error
during POST.
An alarm displays for a failed RAID controller.
2.
Power down the storage blade using the CMC. See the "Powering off the storage system"
instructions in the HP StoreVirtual Storage User Guide.
Wait at least 1 minute for the blade to power down. This procedure flushes all data from the
cache.
CAUTION:
Since the HP 4630 storage system uses external data storage, ensure that the
storage blade is the first unit to be powered down and the last to be powered up. This
precaution ensures that the system does not mark the drives as failed when the storage blade
is powered up.
3.
Remove the storage blade from the blade enclosure.
4.
Remove the top cover from the storage blade.
5.
Remove the failed P721m controller.
6.
Remove the cache module from the failed P721m controller.
7.
Install the replacement P721m controller in slot 2. Connect the cache module and capacitor
pack to the controller.
8.
Reinstall the top cover on the storage blade.
9.
Reinstall the storage blade (in the same bay) in the blade enclosure chassis.
After replacing the P721m controller, verify the BIOS settings and ensure the P220i controller
is set as the boot controller. Otherwise, the storage blade will not boot through the LeftHand
OS software.
10. Power on the storage blade.
