Beforeyoubeginamigration,examineyourcurrentdiskarraytodeterminewhether:
• The physical drives in your array can support the target RAID level.
• Thereissufcientcapacitytoaccommodatethetargetlogicaldrivesize.
Ifyouneedtoaddphysicaldrivestoyourarray,besurethereareunassignedphysicaldrivesinstalledinyour

creatInG a lun clone
ALUNcloneisanexactcopyoftheoriginalLUNorlogicaldrive,includingallthedataitcontains,atonepoint
in time. Use a LUN clone as a backup or to migrate a LUN from one system to another.

thelogicaldriveisofineitisnotavailable,i.e.noreadorwriteoperationsarepossible.
ALUNclonehasthesamecapacity,stripesize,readandwritepoliciesastheoriginalLUN.However,theLUN
clone can be a different RAID level. The choice of RAID levels depends on the disk array. And if you have multiple
diskarrays,youcancreatetheLUNcloneonadifferentdiskarraythantheoriginalLUN.
This action requires SuperUser or PowerUser privileges.
To create a LUN clone of a logical drive:
1. Click the Storage tab.
2. Click the Logical Drive icon.
The Logical Drive list appears.
3. Clickthelogicaldriveyouwant,thenclicktheLUN Clone button.
