Disk Groups and Virtual Disks 65

On the target storage array:

Insert the exported physical disks into the available physical disk slots.

Review the Import Report for an overview of the disk group that you are

importing.

Check for non-importable components.

Confirm that you want to proceed with the import procedure.

NOTE: Some settings cannot be imported during the import disk group procedure.

The following settings are removed/cleared during the procedure:

• Persistent reservations

• Host-to-virtual disk mappings

• Virtual disk copy pairs

• Snapshot virtual disks and snapshot repository virtual disks

• Remote mirror pairs

• Mirror repositories

Storage Array Media Scan

The media scan is a long-running operation that examines virtual disks to

verify that data is accessible. The process finds media errors before normal

read and write activity is disrupted and reports errors to the event log.

Errors discovered by the media scan include:

• Unrecovered media error — Data could not be read on the first attempt or

on any subsequent attempts. For virtual disks with redundancy protection,

data is reconstructed, rewritten to the physical disk, and verified and the

error is reported to the event log. For virtual disks without redundancy

protection (RAID 1, RAID 5, and RAID 6 virtual disks), the error is not

corrected but is reported to the event log.

• Recovered media error — Data could not be read by the physical disk on

the first attempt but was successfully read on a subsequent attempt. Data

is rewritten to the physical disk and verified and the error is reported to the

event log.

• Redundancy mismatches error — The first 10 redundancy mismatches

that are found on the virtual disk are reported to the event log.
