Add or Remove Drives from the Media Validation Partition (Pool)

Dedicate drives to a special Media Validation partition containing T10000C/D or IBM LTO6+ drives. These drives are reserved for media validation requests only.

The partition can only contain drives (not storage cells). Hosts cannot access the drives within the MV partition. The library automatically cleans MV drives regardless of the auto clean status for other partitions or individual drives in the MV pool.

Note:

When adding or removing drives from the MV partition, affected partitions will temporarily go OFFLINE.

1. Click Partitioning in the left navigation area of the GUI.
2. Click Assign Cells .
3. To add a drive — From the first Move Cells drop-down list, select the source partition to move the drive from (if you have not partitioned the library, select the DefaultPartition). From the second drop-down list, select Media Validation.

   To remove a drive — From the first drop-down list, select Media Validation. From the second drop-down list, select the destination partition to move the drives to.

4. Click a module that contains drives (the green arrow below a module indicates the currently selected module).
5. Choose a Select Cells By method. This determines how many resources are selected when you click.
   • Cell-by-cell – Assign cells one at a time by clicking individual cells.
   • Cell Block – Assign like-cells in a rectangular block (two clicks required). Click the top-left corner of the block, and then click the bottom-right corner of the block (do not click-and-drag).
   • Column – Assign all like-cells in a column by clicking any cell in the column.
   • Side – Assign all cells on a side (front or back) by clicking any cell on the side.
   • Row – Assign all like-cells in a row by clicking any cell in the row.
   • Module – Assign all cells currently assigned to the source partition in a module by clicking any cell in the module.
6. Click a T10000C/D drive, IBM LTO6+ drive, or an empty drive bay to add/remove. You can add non-supported drives, however these will not be used for media validation.

   Note:

   Hovering over a drive will show the drive type.

   On the cell map, media validation drive bays are indicated by MV .

7. Click Next, and then apply the changes.

Partitioning Cell Map Legend

Various symbols are used to depict the type of cell on the partitioning screen.

Cell Map Icon	Meaning
	Tape - indicates that the cell is occupied or the drive is mounted.
(no color overlay)	Unallocated - cell assigned to the source partition (in this case partition with ID 1).
(yellow overlay)	Allocated - cell assigned to the destination partition (in this case partition with ID 21)
(red overlay)	Unselectable - cell assigned to a partition that is not one of the partitions currently selected in the drop-down lists. Or, the cell is a system cell. System cells cannot be assigned to any partition.
	CAP cell - you cannot assign these cells to a partition. The CAP cells assigned to the partition depend on the CAP pool.
	Inaccessible - a system cell. You cannot add these cells to a partition and hosts cannot access these cells.
