D20 Hot-Plug Disk Drives - IBM pSeries 7311 D10 Service Manual

D20 Hot-Plug Disk Drives

Attention: The Linux operating system does not support these hot-plug procedures. Also, Linux does not
support hot-plugging any hot-pluggable PCI adapters. Systems with Linux installed on one or more
partitions must be shut down and powered off before replacing any PCI adapter assigned to a Linux
partition. Follow the non-hot-pluggable adapter procedures when replacing a PCI adapter in any partition
with Linux installed.
Before performing the following procedure, read "Safety Considerations" on page 41.
Note: You do not have to power off the system to remove a hot-plug disk drive. Before you perform these
procedures, ensure that the customer has taken appropriate actions to back up the data for the
drive you are removing, and that the drive has been removed from the configuration. Physically
removing a hot-plug disk drive from the system before it has been removed from the system
configuration can cause unrecoverable data corruption.
