You can create Thin Image data pools using HDvM - SN. For information about the creation of DP pools, see the Provisioning Guide for your storage system.
According to the capacity of the pool to create, you must add shared memory.
For details about the relation between shared memory to add and the pool capacity, see Thin Image shared memory requirements. Note: You can only register volumes that you have not already registered as a pool-VOL.
For more information about data pool requirements, including the maximum number of pool-VOLs, see Thin Image data pool requirements.
You can add external and internal volumes to data pools.
Note: There are limitations to adding external and internal volumes to data pools.
For more information about these limitations, see the requirements for Thin Image pool-VOLs listed in Thin Image volume requirements.
You must have the Storage Administrator (Provisioning) role.
In CCI, use the raidcom add snap_pool command.
