30 Event descriptions
207
Error Vdisk scrub completed and found an excessive number of errors in the indicated vdisk.
This event is logged as Error severity when more than 100 parity or mirror mismatches are found and
corrected during a scrub or when 1 to 99 parity or mirror mismatches are found and corrected during
each of 10 separate scrubs of the same vdisk.
For non-fault-tolerant RAID levels (RAID 0 and non-RAID), media errors may indicate loss of data.
Recommended actions
• Resolve any non-disk hardware problems, such as a cooling problem or a faulty controller module,
expansion module, or power supply.
• Check whether any disks in the vdisk have logged SMART events or unrecoverable read errors.
• If so, and the vdisk is a non-fault-tolerant RAID level (RAID 0 or non-RAID), copy the data to a
different vdisk and replace the faulty disks.
• If so, and the vdisk is a fault-tolerant RAID level, replace the faulty disks. Before replacing a disk,
confirm that a reconstruction is not currently running on the vdisk. It is also recommended to make
a full backup of all the data on the vdisk before replacing disks. If more than one disk in the vdisk
has errors, replace the disks one at a time and allow reconstruction to complete after each disk is
replaced.
Warning Vdisk scrub did not complete because of an internally detected condition such as a failed disk.
If a disk fails, data may be at risk.
Recommended actions
• Resolve any non-disk hardware problems, such as a cooling problem or a faulty controller module,
expansion module, or power supply.

has errors, replace the disks one at a time and allow reconstruction to complete after each disk is

Info. Vdisk scrub completed or was aborted by a user.
This event is logged as Informational severity when fewer than 100 parity or mirror mismatches are found
and corrected during a scrub.
For non-fault-tolerant RAID levels (RAID 0 and non-RAID), media errors may indicate loss of data.
Recommended actions
• No action is required.
208
Info. A scrub-disk job has started for the indicated disk. The result will be logged with event 209.
