While the x335, BladeCenter, x345, and x360 are all high-reliability units,
occassionally a component may fail. Two areas that might cause problems are:
1. Disk drives
2. Systemboard
Disk drive failure on the Management Node
The x345 supports hot swapping of hard disks. To replace a failing hard disk on
the Management Node:
1. Remove the failing hard disk by sliding it out through the front panel opening.
2. Slide the replacement disk drive into the open slot. The drive will rebuild
automatically on a mirrored system. If the system is not mirrored a complete
re-install of the Management Node is required. See Chapter 6, “Software
installation”, on page 35 for detailed instructions.
Disk drive failure on a Cluster Node
The x335 supports hot swapping of hard disks, but BladeCenter does not. To
replace a failing hard disk on an x335:
1. Remove the failing hard disk by sliding it out through the front panel opening.
2. Slide the replacement disk drive into the open slot.
3. At the Management Node, issue the following command:
installnode x
where x is the number of the node being rebuilt. If needed, have the customer
contact support to assist with the correct naming conventions and IP addresses.
If a hard drive fails on a Blade server in the BladeCenter, first power down the
Blade server. Next, remove the Blade server from the BladeCenter and replace the
hard drive as outlined in
IBM eServer BladeCenter Hardware Maintenance Manual and
Troubleshooting Guide . Once the drive is replaced and the Blade server is returned to
the BladeCenter issue the following command at the Management Node:
installnode x
