Select Pool VOLs window

Use this window to add pool-VOLs to a pool. Only LDEVs assigned to the logged-on user are available.

Available Pool Volumes table

Only the LDEVs assigned to the user are displayed.


Item	Description
LDEV ID	Displays the LDEV identifier, which is the combination of LDKC, CU, and LDEV.
LDEV Name	Displays the LDEV name.
Capacity	Displays the pool-VOL capacity.
Parity Group ID	Displays the parity group ID.
RAID Level	Displays the RAID level. If an LDEV is an external volume, a hyphen (-) is displayed.
Drive Type/RPM	Displays the data drive type and RPM. When the volume is the external volume, Drive Type displays External Storage.
Provisioning Type	Displays the type of the LDEV. Basic: Internal volume. External: External volume.
Attribute	Attribute of the volume indicating how the LDEV is being used. Data Direct Mapping: LDEV of the data direct mapping attribute. Hyphen (-): Volume in which the attribute is not defined.
Cache Mode	For the external volume, this item displays whether the cache mode is enabled. If the LDEV is not an external volume, a hyphen (-) is displayed.
Encryption	Displays the encryption information about the pool. Enable: Encryption setting of a parity group or pool-VOL containing LDEV is enabled. Disable: Encryption setting of a parity group or pool-VOL containing LDEV is disabled. Mixed: In the pool, pool-VOLs whose encryption settings are enabled or disabled are intermixed in the pool in which the LDEV is placed. Caution: The data encryption is not ensured in the pool that has the Mixed encryption setting. To manage the data encryption securely, use the pool with an encryption setting of Enabled or Disabled. Hyphen(-): External volume. Virtual Storage Platform G200.
Accelerated Compression	Displays information about the accelerated compression of the parity group that is created of LDEVs. Enabled: The accelerated compression of the parity group is enabled. Disabled: The accelerated compression of the parity group is disabled. Hyphen (-): accelerated compression is not supported on the parity group.
Resource Group Name (ID)	Displays the resource group names and IDs of the LDEV. The ID is provided in parentheses.

External LDEV Tier Rank

Specify the tier rank of the external volume. If there is no external volume in the Available Pool Volumes table or Selected Pool Volumes table, you cannot select this option.

Add

When you select a row in the Available Pool Volumes table and click Add, the selected pool-VOL is added to the Selected Pool Volumes table.

Up to 1,024 volumes can be added including the volumes already in the pool.

When adding a volume to the pool for which Multi-Tier Pool is enabled, note the following:

For a pool, you can add volumes whose Drive Type/RPM settings are the same and whose RAID Levels are different. For example, you can add the following volumes to the same pool:

Volume whose Drive Type/RPM is SAS/15K and whose RAID Level is 5 (3D+1P)

Volume whose Drive Type/RPM is SAS/15K and whose RAID Level is 5 (7D+1P)

For details about adding of LDEVs carved from the accelerated compression-enabled parity groups, see Guidelines for creating a pool when accelerated compression is used .

Remove

When you select a row in Selected Pool Volumes table and click Remove, the selected pool-VOL is removed from the Selected Pool Volumes table.
