POOL_ID

The pool ID of the Dynamic Provisioning pool, Copy-on-Write Snapshot pool, or Thin Image pool to which the logical device belongs. A value is stored in this field for the following types of logical devices only:²

• A Dynamic Provisioning V-VOL or a pool volume.
• A Thin Image V-VOL or a pool volume.

However, the value for Thin Image V-VOL is stored in this field only when the V-VOL is associated with the Dynamic Provisioning pool.

string(64)

RAID_LEVEL^{6, 7, 8}

unsigned char

RAID_TYPE^{3, 4, 5}

Note that the following format is used for a volume split from a distributed parity group:

• Example when the Access Type is 1 or 2

  RAID1(4D+4D)

• Example when the Access Type is 3 or 4

  RAID1(2D+2D)x2

VIRTUAL_DKC_NAME^{9, 10, 11, 13}

Product name of the virtual storage machine to which the logical device belongs.

string(32)

VIRTUAL_LDEV_NUMBER^{9, 12}

Virtualized logical device number associated with the logical device.

string(16)

VIRTUAL_SERIAL_NUMBER^{9, 10}

Serial number (in decimal) of the virtual storage machine to which the logical device belongs.

string(32)

VOLUME_TYPE

Information that indicates whether the logical device is a type of V-VOL (a Dynamic Provisioning V-VOL or Thin Image V-VOL) or a type of pool volume (Dynamic Provisioning pool volume, Copy-on-Write Snapshot pool volume, or Thin Image pool volume). If the logical device is a V-VOL for Dynamic Provisioning or Thin Image pair, information is stored in this field only when the V-VOL is associated with the Dynamic Provisioning pool:²

string(16)

Notes:

1. If the logical device is a component of a LUSE, this field only stores the record for the first logical device of the LUSE.

   If the LUSE consists of external volume, or logical devices of V-VOLs for Copy-on-Write Snapshot/Thin Image or Dynamic Provisioning, and no LU path is set for the LUSE, the LUSE is not recognized and records are created for individual logical devices. In this case, the PD_LSEC record is not created for individual logical devices.

2. When the pool to which the logical device belongs is blocked, this field becomes empty unless the usage rate of the pool capacity is 100%.
3. The value cannot be collected when the logical device is a Dynamic Provisioning V-VOL.
4. The value cannot be collected when the logical device is a Copy-on-Write Snapshot V-VOL or a Thin Image V-VOL.
5. The value cannot be collected if the logical device is an external volume.
6. The field value is always 0 when the logical device is a Copy-on-Write Snapshot V-VOL or a Thin Image V-VOL.
7. The field value is always 0 when the logical device is a Dynamic Provisioning V-VOL.
8. If the logical device is an external volume, the field value will always be 0.
9. If the logical device does not belong to a virtual storage machine, the field value will be NULL.
10. If the logical device that composes a copy pair of global-active device is not virtualized, the field value will be NULL.
11. If the virtual storage machine is VSP F400 or VSP F600, the value is VSP G400 G600. If the virtual storage machine is VSP F800, the value is VSP G800.
12. If either of the following applies to the logical device, the field value will be NULL:
    • The logical device that is part of a copy pair of a global-active device is not virtualized.
    • A virtualized logical device number is not set.
13. If the virtual storage machine is VSP G1000, the value stored in the VIRTUAL_DKC_NAME field is VSP G1000 G1500 F1500.
