Replacing a server blade
This section describes the implications for the HP P4800 G2 solution software and not the
mechanical aspects of replacing the server blade.
WARNING!

not swap or move server blades in a blade enclosure or disk enclosure in HP P4800 G2 solution
systems. If you do, nodes will lose failover ability and you may lose connectivity to the disks and
network.

time. When removing an active component, immediately replace it with a blank.
IMPORTANT:
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.
IMPORTANT:
re-imaged using a recovery CD. Doing so requires that the administrator access the console of the
blade through the iLO (or blade KVM 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.
IMPORTANT:
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.
To prepare the server blade for replacement:
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 server blade is configured with a static or reserved IP address and not
DHCP. If necessary, convert the server blade to a static or reserved IP address. Record this IP
address for verification after the process is complete.
3. Record the MAC address.
Record the MAC address of the old blade for later use. Also record the server 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 blade.
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.
To replace the server blade or its system board:
1. Power down the server blade.
To power down the server blade from the CMC, see the "Powering off the storage system"
instructions in the HP P4000 SAN Solution User Guide.
2. Note the server blade bay number, and then remove the server blade from the blade enclosure.
