Changing RAID size

Valdez-IT — Sat, 19 Jan 2008 01:19:55 GMT

I have a DL 380 running raid 5. One partition is 10gigs and the other is 400gigs. I need to increase the size of the 10gig partition by 10gigs and decrease the 400gig partition to 390gigs? I can not reimage the box or anything like that. I am able to reboot it if need be. Any suggestions?

hi

well if you just want to do that increase one partition taking space from another

you have to use partitioner software like:

Partition Manager 8.5

or

AcronisÂ® Disk Director Server 10.0

You may be able to expand the LUN in Command View. Under Virtual Disks properties there is a capacity section. Request more capacity. On a Windows host you would then use diskpar rescan the disk to 'see' the additional storage.

I was told in a CV class that the EVA 8100 supports 'LUN Shrink' in which you would simply request less storage space in the Capacity field for the vDisk. But, I have not tested this procedure.

Each OS handles dynamic increases in storage volumes differently (Windows, VMware, HPUX). I'd test this out on your Windows host by presenting a small LUN, put some data on it, then expand the LUN and make sure no data is lost.

Hope this points you in the right direction.
