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

6. Power on the blade bay.
CAUTION:
• Be sure to only replace a storage blade in the bay from which it was removed. Do not swap
or move storage blades in a c7000 blade enclosure. If you do, nodes will lose failover ability
and you may lose connectivity to the disks and network.
• For cooling practices, do not leave a server bay open for an extended period of time. When
removing an active component, immediately replace it with a blank.
IMPORTANT:
• If the boot disk(s) from the blade being replaced are available, placing them in the new blade
allows it to boot to its original configuration. Do not reset the network settings if you are using
the original boot disk(s) on the blade being replaced.
• If the original boot disk(s) are not available or are damaged, the blade must be re-imaged
using a recovery DVD. Doing so requires that the administrator access the console of the blade
through the iLO (or SUV dongle) to set the server name and IP address. If you are not using
the original boot disk(s), be sure to reset the network settings.
• The HP 4630 system should handle a single blade failure for an extended period of time
without loss of data or lost access to the data. The cluster, however, will remain in a degraded
state until the replacement blade is functioning.
Replacing a storage blade system board
Prepare the system board for replacement
NOTE: The following steps can only be performed if the storage blade is bootable and accessible
from the CMC. If the storage blade does not boot, skip these steps and go to “Replace the system
board”.
1. Confirm the RAID and customer data.
Ensure that RAID is configured on the old blade and that the customer data exists on the disk
enclosures.
2. Confirm the IP address.
Ensure that the existing storage blade is configured with a static or reserved IP address and
not DHCP. If necessary, convert the storage blade to a static or reserved IP address. Record
this IP address for verification after the process is complete.
3. Record the MAC address (only if the FlexLOM needs to be replaced).
Record the MAC address of the FlexLOM for later use. Also record the storage blade hostname
for later verification.
4. Delete the NIC bond.
Delete any NIC bond previously established on the old blade by using the console or the
CMC. The NIC bond must be deleted because it retains the MAC address of the old FlexLOM.
If you are unable to delete the NIC bond at this time, make sure to delete it on the power
cycle following the blade swap.
Replace the system board
1. Power down the storage blade.
To power down the storage blade from the CMC, see the “Powering off the storage system”
section in the HP StoreVirtual Storage User Guide.
