Sun StorageTek Common Array Manager Software Release Notes 19
CSM200 Best Practices
When you add a new CSM200 expansion module to an existing array in a
production or active environment, it is best practice to cable and add the trays while
the RAID controller module is powered on.
Before connecting any replacement drive or additional expansion module to an
existing functioning array, it is best practice to contact Sun Microsystems Support
Services. One reason for this is to avoid issues related to DACstore, the configuration
and status database maintained by the array firmware, that stores its information on
each of the disk drives.
Because corrective actions for a DACstore issue may require a configuration
restoration, it is important to maintain a current image of the configuration. And, as
always, it is best practice to maintain recoverable backups of your data.
Affected arrays are:
■ Sun StorEdge 6130 Array
■ Sun StorageTek 6140 Array
■ Sun StorageTek 6540 Array
■ StorageTek FLX280 Array
■ StorageTek FLX380 Array
Contact Sun Microsystems Support Services promptly upon experiencing any of the
following symptoms:
■ loss of management or data access
■ inability to apply feature licenses
■ inability to upgrade/install the baseline for array firmware
■ incorrect component details in the management tool
■ host operating system reports the wrong product identifier
■ array registration or discovery fails to complete
■ persistent or unrecoverable multipathing failover
