9.9.1 Operations after Replacement of a SAS Module or an
Expansion Card Slot Module
If the SAS module or the expansion card slot module is replaced due to an error when the array
controller function is used for this Server Blade, the logical drive of the array controller is initialized
again after replacement. This is because the data integrity information showing whether data was written
correctly on internal hard disk unit in the past is stored in the SAS module or the expansion card slot
module. As the information is lost due to replacement, the initialization is automatically executed to
ensure the data integrity.
You can restore this information using maintenance tool just before the replacement and write back after
the replacement, however, if you cannot restore the information because of the malfunction of the SAS
module or the expansion card slot module, the initialization procedure starts. This does not mean hard
disk failure as well as the initialization.
For details of the initialization, refer to the manual in the Array controller Document & Tool CD.
