label info has changed for disk C5P1. write out changes? (yes)
As Irix writes the disk label to the RAID Array, an error message is usually displayed on
the system console. The error message reads:
dks10d64: [Alert] Illegal Request: Illegal Field in CDB………
This message is caused by the Host adapter sending an illegal command to the RAID
Array. The error message can be ignored.
Partitioning the Storage
After the disk label has been successfully written, the storage can be divided into the slices
or partitions that are required by the user application. Since it is not possible to alter the
partition structure of the storage device once it contains user data, this step should be
carefully planned. A few factors to consider when deciding on the partition/slice size
include:
■ Total storage space required for application and user data, now and in the future
■ Maximum amount of storage space in one partition that can be addressed by the
application
■ Backup time, strategy, and tool capabilities
The following simple example, shows ID 64, LUN 4 being partitioned with the default
partition allocation used by the fx utility.
