Owners Manual

The trust command attempts to resynchronize leftover disks to make any leftover disk an active member of the disk group.
The trust command may be needed when a disk group is offline because there is no data backup. The trust command may
also be needed as a last attempt to recover the data on a disk group. In this case, the trust command may work, but only if
the leftover disk continues to operate. When the "trusted" disk group is back online, backup all data on the disk group and verify
all data to ensure it is valid. Then delete the trusted disk group, add a new disk group, and restore data from the backup to the
new disk group.
CAUTION: Using trust on a disk group is only a disaster-recovery measure. The disk group has no tolerance for
another failure and should never be put back into a production environment. Before trusting a disk group,
carefully read the cautions and procedures for using the trust command in the Dell EMC PowerVault ME4 Series
Storage System CLI Reference Guide and online help. If you are uncertain whether to use this command,
contact technical support for assistance.
Once the trust command has been issued on a disk group, further troubleshooting steps may be limited towards disaster
recovery. If you are unsure of the correct action to take, contact technical support for further assistance.
