RequirementItem
To maintain performance levels, use the following configurations:
• Place normal volumes and pool-VOLs in separate parity groups (see “Fast Snap
licensed capacity requirements” (page 27)).
• Ensure that pool-VOLs consist of LDEVs from more than one parity group.
You cannot specify the following volumes as FS pool-VOLs:
• Volumes that have a volume status other than “Normal” or “Normal (Quick Format)”.
Note: While you are blocking or copying a volume, you cannot specify the volume.
• Volumes that are already being used as FS P-VOL or S-VOLs.
• Volumes that are already contained in FS, THP, or Smart pools.
• Volumes used as migration plans or pair volumes for another product.
• Volumes for which you have used the Data Retention to set Read Only, Protect, or
S-VOL Disable attributes.
• Cache Residency volumes.
• Command device volumes.
Note: The following restrictions apply to volumes used in the same data pool.
• Volumes must be in the same resource group.
• External pool-VOLs must have the same cache mode, either enabled or disabled.
• When using both internal and external volumes, the external volumes must have
cache mode enabled.
OPEN-VEmulation type
All RAID levels are supported. However, you cannot contain pool-VOLs of different
RAID levels in the same pool.
RAID level
You can use SAS and SSD.Data drive type
If you use internal and external volumes, you can use pool-VOLs with different drive
types in the same pool. For best performance, use pool-VOLs with the same drive type
in the same pool.
For more information about data drive type, see “Pool creation and data drive type
priority” (page 41).
Registering pool-VOLs to Cache Logical Partition Numbers (CLPRs) in pools: You can
register pool-VOLs assigned to different CLPRs in a pool (see “Workflow for registering
virtual volumes” (page 42)).
CLPR
Changing CLPRs: You can change CLPRs in the parity group belonging to the pool-VOL.
In this case, regardless of the CLPR in the pool-VOL, the CLPR number in the parity
must be the same as that of the P-VOL that you are using (see “Changing CLPR numbers”
(page 60)).

Define only needed paths to a volume so that you can specify the volume as a pool-VOL.Path definition
Fast Snap data pool requirements
The following table lists the requirements for FS data pools.
RequirementItem
Calculate the pool capacity (see “Calculating and assigning pool capacity”
(page 34)).
