ERL=1: Digest Failure Recovery

ERL=1, only applies to traditional iSCSI. For iSCSI/SCTP (which has its own

CRC32C) and both types of iSER (so far), handling header and data checksum

recovery can be disabled.

ERL=2: Connection Recovery

ERL=2, allows for both single and multiple communication path sessions

within a iSCSI Nexus (and hence the SCSI Nexus) to actively perform

realligence/retry on iSCSI ITTs from failed iSCSI connections. ERL=2 allows

iSCSI fabrics to take advantage of recovery in all regards of transport level

fabric failures, and in a completely OS independent fashion (i.e. below the host

OS storage stack).

Disk Clone and Wipe

Disks installed on this device are able to utilize the Disk Clone and Wipe function

Disk Clone:

Unused Disks that have been installed on this storage device can utilize the disk

clone function. If disks have already been configured in a RAID volume or as a

spare disk, they cannot perform disk clone.

To start disk clone, select the source disk from the drop down menu and target a

disk from the dialog box as seen below. Carry on to press “Apply,” then the task will

start. It may take a few hours depending on the size of the disk.

Please be sure the source disk is equal to or smaller than the target disk.

Disk Wipe:

Disk Wipe is able to erase data from selected disks. Again, disks that have already

been configured in a RAID volume or as a spare disk cannot perform this function.
