Parameters

Parameter

Description

physicalDisks

The physical disks you want to assign to the disk
pool. Enclosure ID values are 0 to 99; drawer ID
values are 0 to 4; slot ID values are 0 to 31.

NOTE: A disk pool must contain at least 11
physical disks.

physicalDiskType

Physical disk type value is sas. Enclose the
physical disk type values in parentheses. If the
physical disk type is specified, then all of the
unassigned physical disks of that type that are
compatible with each other are used for the
creation of the disk pool.

physicalDiskCount

The physicalDiskCount parameter limits the
disk pool candidates to the given number. Use this
parameter only when the physicalDiskType
parameter is specified.

reservePhysicalDiskCount

The default value is automatically determined by
the RAID controller module. This value is specified
in terms of the number of physical disks to reserve
in the disk pool for physical disk failures or physical
disk removals.

warningThreshold

The percentage of storage capacity at which you
receive a warning alert that the disk pool is nearing
full capacity. Use integer values. For example, a
value of 60 means 60 percent. The default value is
50.
Setting this parameter to 0 disables warning alerts.
If you set this to default, the warning alert

threshold value is determined by the RAID

controller module firmware.

criticalPriority

The default value is highest.

backgroundPriority

The default value is low.

securityType

The setting to specify the security level when
creating the disk pool. All virtual disk candidates for
the disk pool have the specified security type.
These settings are valid:

• none—The virtual disk candidates are not

secure.

• capable—The virtual disk candidates are

capable of having security set, but security has

not been enabled.
