Dell EMC XtremIO plug-in considerations and limitations
The following considerations and limitations are applicable:
All the snapshots taken for any volume are read-only. A new re-purpose copy, cloned from the snapshot volume, is used for data backup.
The limit for any volume name is 128 characters on the array. For a repurpose copy, the maximum length of the volume name is 128 - (23(NB<unique_21digit_number>) - 9(Repurpose) - 2(Dot notations)) = 94. It is a strict requirement to limit the volume name to 94 characters for a successful snapshot.
Do not write data to the repurpose copy created by NetBackup by manually mapping it to a host. You can consider the re-purpose copies created by them as an individual volume in NetBackup. Do not use the copies starting with volume_name.NB<unique_21digit_number>.repurpose.
Do not refresh the repurpose copy, as this changes the data on the image by refreshing from the parent volume. This affects backup and restore.
