The mkrank command creates one fixed block or count key data (CKD) rank from one array.
>>-mkrank--+-------------------------+-- -array--array_ID-------> '- -dev--storage_image_ID-' >-- -stgtype--+-fb--+--+--------+-------------------------------> '-ckd-' '- -wait-' >--+--------------------------+-------------------------------->< '- -extpool--extentpool_ID-'
Parameters
Note: It is recommended that you specify either the -wait or
the -extpool parameter when using the mkrank command. Using
either of these parameters allows you to be notified if the rank configuration
has failed for any reason.
- -dev storage_image_ID
- (Optional) Specifies the storage image ID, which includes manufacturer, type, and serial number. This parameter is required if you do not specify a fully qualified ID for the extent pool and you do not specify a value for the devid variable in your profile file.
- -array array_ID
- (Required) Specifies the ID of the array from which the rank is to be created. An array ID is a four digit decimal number with no leading zeroes, prefixed with the letter A.
- -stgtype fb | ckd
- (Required) Specifies the type of extent for which the rank will be configured, either fixed block or count key data.
- -wait
- (Optional) Delays the command response until the rank configuration process completes.
- -extpool extentpool_ID
- (Optional) Specifies the extent pool that contains the created rank extents.
If an extent pool is specified, then the rank will be assigned to the extent
pool. Otherwise, the rank state is unassigned. If specified, the extent pool
must exist and must be compatible with the specified -stgtype parameter
option. An extent pool ID is a four-digit decimal number with no leading zeroes,
prefixed with the letter P.Note: You must use the chrank command if you choose to specify the extent pool ID at a later time.
