This alert is generated when the specified disk in the DPM storage pool cannot be detected or has stopped responding. Until the disk is connected and working properly, all protection activities that rely on this disk will fail.
A disk in the storage pool has been removed or is not working properly.
The error conditions and recommended actions associated with each “Disk missing” alert are provided in the alert details.
Follow the recommended action in the alert to retry the job.
On the Disks tab in the Management task area, check the status of disks. If a disk is missing, rescan the disk configuration to detect the disk. If the disk is still missing, verify physical disk connections and rescan again. If the disk is no longer available, you can remove the disk from the storage pool. To continue protecting the affected data, stop protection of the data sources by using the Delete replica option, and then add the data sources to a protection group again.
If the replica and the recovery point volume are missing, do the following:
- Remove all protected objects from the protection group.
- Use the Create New Protection Group Wizard to reprotect the
objects to the same or to a different protection group.
If only the recovery point volume is missing, do the following:
- Create a replica manually, and add it to the protection group.

To restore protection after replacing a disk:
- In DPM Administrator Console, remove the disk from the storage
pool configuration to prevent future “Disk missing” alerts. For
more information, see How to Remove a Disk
from the Storage Pool.
- DPM allocates disk space for the members on a healthy disk,
creates the replica, and performs a consistency check. Scheduled
synchronization jobs and recovery point creation jobs will resume.
(Recovery points that were stored on the missing disk are no longer
