CLI Guide

5. Unseat the spare disks associated with the disk group to prevent reconstruction.
CAUTION: It is recommended to avoid reconstruction after using the trust command.
Reconstruction causes heavy usage of disks that were already reporting errors. This usage
could cause the disks to fail during reconstruction, which can cause data to be
unrecoverable.
6. Enable the trust command.
7. Run the trust command on the disk group.
8. If the trust command determines that it would be unsafe to proceed, it will fail. If this happens you can
either:
• Contact Support for further assistance. This is recommended.
• Proceed by re-enabling trust and running trust with the unsafe parameter. This is not recommended
because in most cases it will result in an unstable disk group with data corruption.
After running the trust command
1. Reinsert the host-port cables.
2. Perform a complete backup of the disk group.
3. Delete the disk group.
4. Replace the failed disks with new disks.
5. Re-create the disk group.
6. Restore the data from the backup performed in step 2.
7. Restore original disk-group ownership.
8. Re-enable background scrub operations.

[disk-group disk-group]
[unsafe]
[vdisk vdisk]
Parameters

disk-group disk-group
Optional. The name or serial number of the disk group to trust. A name that includes a space must be
enclosed in double quotes.
unsafe
Optional. Specifies to proceed with a trust operation that is determined to be unsafe because it must use
out-of-sync or partially reconstructed disks.
CAUTION: In most cases using this option will result in an unstable disk group with data
corruption.
vdisk vdisk
Optional. The name or serial number of the disk group to trust. A name that includes a space must be
enclosed in double quotes.
Output
