Using Compatible FlashCopy with Thin Provisioning Z
When you use a Compatible FlashCopy T-VOL as a THP V-VOL, the host cannot access it if the
relationship status becomes suspended because the pool becomes full. To recover from suspended
status, you must release the Compatible FlashCopy relationship.
Using Compatible FlashCopy with Resource Partition
You can create a relationship regardless of whether the S-VOL and the T-VOL are assigned to the
same resource group or not.
Using Compatible FlashCopy with Virtual LVI
To create a relationship using Virtual LVI volumes, you need to set the capacity for the S-VOL and
T-VOL.
