Maintenance and Service Guide
■ If at any time, disk drive errors occur and you must contact an HP service
representative, submit the SHOW DEVICE_ERRORS
FMU command prior to
contacting an HP service representative. Submitting the SHOW DEVICE_ERRORS
FMU command generates a report that assists the HP service representative in
resolving device problems. For additional details regarding the SHOW
DEVICE_ERRORS command, refer to the
HP StorageWorks HSG60 and HSG80
Array Controller and Array Controller Software Troubleshooting Guide.
Removing and replacing all disk drives
In all cases (disk drive hot or warm swapping), you must remove the required disk
drive from any unit association and storagesets, including mirrorset, failedset, or
spareset prior to initiating the physical removal. Use the following commands to
complete this action:
HSG prompt> DELETE unit-name or reduce the storageset member (mirrorset
or RAID 3/5)
HSG prompt> DELETE storageset-name or SET mirrorset-name
REMOVE=disknnnnn
HSG prompt> DELETE disknnnnn;
Adding, moving, and changing disk drives
The array controller maintains a configuration map of device types and locations.
This map is used to communicate with devices. If you add, move, or change a
device while the array controller is powered off, without first changing the array
controller configuration, the array controller cannot communicate with the
changed device after its returned to service.
If you remove a disk drive while the array controller is off, delete all containers
associated with the removed disk drive after power is restored to the array
controller. If you have difficulty removing the disks or containers from the
configuration after you restore power, because of cache lost data, power down the
storage subsystem again, remove the power from the cache module (pulling it out
of the backplane of the EMA or MA series enclosure or removing the cache
battery cable to the front of the cache module on RA8000 enclosures), and then
power up and clear the lost data indications.
