InForm OS Version 2.3.1 Command Line Interface Reference

◆ mag. A chunklet from another disk within the same drive magazine can be used as a

replacement.

◆ cage. A chunklet from another drive cage can be used as a replacement.

◆ port. A chunklet from another port can be used as a replacement.

■ CAvail. Indicates the current, or actual, availability: disk, mag, port, or cage.

■ Creation Time. Indicates when the logical disk was created.

The following example displays policy information about all system LDs:

The columns in the previous example are identified as follows:

■ Id. The logical disk ID.

■ Name. The logical disk name.

■ Keep_Preserved. Indicates if preserved data is saved for the logical disk. Valid values are

1 (saved) and 0 (not saved).

■ Dev_Type. Device type for the physical disk (FC for Fibre Channel or NL for Nearline or

SSD for Solid State Device). If no device type is specified, the default is Fibre Channel drives.

If a system has only Nearline drives,

-p -devtype NL must be specified when creating the

volumes.

■ K_RPM. Shows the device speed used by the majority of the chunklets of the logical disk.

The number does not represent a rotational speed for the drives without spinning media

(SSD). It is meant as a rough estimation of the performance difference between the drive

and the other drives in the system. For FC and NL drives, the number corresponds to both a

performance measure and actual rotational speed. For SSD drive, the number is to be

treated as relative performance benchmark that takes into account in I/O per second,

bandwidth and the access time.
