PDISKID=<connector:enclosureID:portID | connector:targetID>
Use this parameter to specify the physical disks that will be included in the virtual disk.
When reconfiguring a virtual disk, you must specify all physical disks to be included in the reconfigured
virtual disk. The physical disk specification applies to physical disks that were in the original virtual disk
and will continue to be in the reconfigured virtual disk and to any new physical disks being added to the
reconfigured virtual disk. Some controllers allow you to remove a physical disk from a virtual disk. In this
case, you would not specify the physical disk to be removed.
The pdisk=<PDISKID> parameter indicates a physical disk by specifying either
connector:enclosureID:portID or connector:targetID.
stripesize=< 2kb| 4kb| 8kb| 16kb| 32kb| 64kb| 128kb>] Parameter
(Optional)
Different controllers support different stripe sizes. See the online help for information on which stripe
sizes are supported for a controller. All stripe sizes are specified in kilobytes. For example, when
specifying 128 KB as the stripe size, enter:
stripesize=128kb
[cachepolicy=<d | c>] Parameter (Optional)
Different controllers support different cache policies. See the online help for more information.
The following table indicates how to specify the [cachepolicy=<d | c>] parameter for each of the
cache policies.
[readpolicy=<ra| nra| ara| rc| nrc>] Parameter (Optional)
Different controllers support different read policies. See the online help for more information.
The following table indicates how to specify the [readpolicy=<ra| nra| ara| rc| nrc>] parameter for
each of the read policies.
