Hi

With the following error message from a MSA2324sa, will it be possible to bring the vdisk online and hopefully access the date ?

Hi,

As per the events, one of the Disk is failed and immediately Vdisk is Went down.

Is the Vdisk named vd04 is confgiured on RAID 0?? IF so it is difficult.

Contacting support center would be the best solution if u have critical data on that vdisk.

If the status of the vdisk that originally had the failed disk status is FATAL FAIL, one or more disks have failed in a RAID-0 vdisk; two or more disks have failed in a RAID-1, 3, or 5 vdisk; or three or more disks have failed in a RAID-6 vdisk.
--------------------------------------------
In that case all data in the vdisk is lost. Use the CLI trust command to attempt to bring the vdisk back online.
---------------------------------------------
Enables an offline vdisk to be brought online for emergency data collection. This command must be enabled before each use.

CAUTION: This command can cause unstable operation and data loss if used improperly. It is intended for disaster recovery only.
--------------------------------------------
A vdisk is offline because a disk is failing, you have no data backup, and you want to try to recover the data from the vdisk. In this case, trust may work, but only as long as the failing disk continues to operate.
--------------------------------------------
When the â trustedâ vdisk is back online, back up its data and audit the data to make sure that it is intact. Then delete that vdisk, create a new vdisk, and restore data from the backup to the new vdisk.
-------------------------------------------
Example: Enable the trust command and then trust vdisk VD1:
# trust enable
Trust Virtual-disk Enabled.
# trust vdisk VD1
Are you sure? yes
Virtual-disk VD1 has been trusted.
