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.
