Hi,

In virtual Pool data in Pool is spread across disk groups.
Even if one of the disk groups in a Pool fails the entire Pool will fail.
Exception is read cache disk group failure.
Once a disk group fails replacing the disks will not bring it out of quarantine state.
Please log an HPE support case to check for options to either bring Pool back online or delete the Pool.
Please retain the original failed disks with you till HPE support reviews the logs.

Got it, as you said.  we lost the data in the B pool. We're working with the HPE support team to delete and recreate the B pool.

thanks for the answer.
