change Raid1 to Raid5 on MSA2252fc
Hi Experts,
I have a HP storage MSA2252fc.
One vdisk is a raid1 for our SQL server.
But the space is less now.
Is it possible to change raid from 1 to 5 with the MSA ?

Changing raid is always deleting the whole array. You can not migrate raid levels. So if you can export the date you can change the raidlevel. after you import again after the downtime.
As noted, you can't change RAID types on the fly. You can either back the data up, re-create the RAID, and then restore the data, or you can add a new RAID, and then move the data from the old one.
hi mate,
As I remember from my integration of some MSA 2000 series arrays, they don't support RAID level migration, so migrating from RAID 1 to RAID 5 is just not possible. Additionally it is rather not good option to migrate SQL (database) server to RAID 5. I don't know your financial situation and company size but in such situation I will evidently show situation to the managers or directors of a company and asks them for money for another disks or another cage with disk if yours is full. I know it's sometimes looks impossible to get more unplanned money in smaller companies and even in the bigger ones, but truly talking with managers about possibilities and effects of ending space on SQL server may be really devastating of an application, runtime, or even DB itself which costs will be in most cases much higher than another disks to array or even cage with some disks.
The true secret of making some things better is awareness and education of higher level managers of a company with lower level problems and costs of doing nothing and not take care of problem before it move to be critical.
So conversation with company managers should be done immediately and You have to convert them to get some money for new disks.
this is my opinion that I also offer many times to my customers, IT Admins, technical guys, managers and directors.

ok thats what I want to know. MSA2000 cannot raid migrations.
So I will setup a new raid or put in bigger disks.
With my raid 1 can I mix the speed of disks ?
