Replacing a Disk Storage Module
This section describes the concurrent repair procedure to replace a Disk Storage
Module (DSM) in an IBM BladeCenter S chassis.
About this task
A DSM is an enclosure holding up to six disk drives. Concurrent DSM replacement
is only supported with RAID 1 and RAID 10 configurations where storage pool
enclosure redundancy has been configured. You can also concurrently replace a
DSM if there are no storage pools using the disk drives in the DSM. You can verify
storage pool enclosure redundancy by reviewing the detail pool data using the
RAID Controller command line interface (CLI) or the IBM Storage Configuration
Manager.
Note: If your DSM does not meet the requisites for concurrent replacement, follow
the steps in “Replacing a Disk Storage Module (non-concurrent procedure)” on
page 161.
Perform the following steps to concurrently replace a DSM using the RAID
Controller CLI. Information enclosed in “<>” is specific to the local system
configuration.
Procedure
1.
Log in to the RAID Controller CLI.
2. At the
<CLI>
prompt, enter
list pool
and press Enter to list the summary for
each storage pool. Ensure the storage pool is not degraded and the status is
viable.
<CLI> list pool

ONF/OFF/SF=Online Failed/Offline Failed/ Service Failed
ONV/OFV/SV= Online Viable/Offline Viable/Service Viable
ONN=Online Non-viable/Pending Non-Viable; one or more drives are missing in this
pool.
The pool state changes to ONV if missing drive(s) comes back to the pool.
The pool state changes to OFN if the user acknowledges the alert.
3. Enter
detail pool –name <STORAGE_POOL_NAME>
and press Enter to list the
detailed information for the storage pool. For the
<STORAGE_POOL_NAME>
, use
the storage pool name shown in the list pool output from the previous step.
The number of disk drives configured for the storage pool must be equivalent
between the primary and secondary section, and evenly distributed between
each DSM. In the following example, six disk drives are configured in a
RAID10 storage pool configuration. Three disk drives in the primary section
are in DSM 2, and three drives in the secondary section are in DSM 1.
<CLI> detail pool -name RAID10_Pool
