change RAID 5 to RAID 1, P410i and ESXi 5 ("raid=1" is not a valid option for logicald

[pirx4711]

Hi,

I mistakenly installed ESXi 5 on a new DL580G7 host with 3 disks in RAID5. Now I want to change that to RAID 1 + spare which is our default.

I already tried to modify the RAID level with hpacucli command, but the direct step from R5 to R1 seems not to be possible. Would it be possible if I first migrate to RAID 0 and in a second step to RAID 1?

=> ctrl all show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 5001438020BC06E0)

   array A (SAS, Unused Space: 0  MB)


      logicaldrive 1 (558.7 GB, RAID 5, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 300 GB, OK)
      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 300 GB, OK)
      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 300 GB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 5001438020BC06EF)

=> ctrl slot=0 ld 1 modify raid=1

Error: "raid=1" is not a valid option for logicaldrive 1

Available options are:
   raid 0
   raid 5 (current value) (default value)

Hi Pirx4711,

You have a RAID 5 partition of 558.7GB.
 and only 3 hard drives of 300GB each.

You want to configure RAID1 partition of 300GB + spare drive.

You can't reduce the size of logical partition hence you couldn't see the option for RAID 1 migration.

If install 2 additional drives then you could configure it for RAID 1+0 (4 drives) + 1 spare drive

If want to meet your standard then there is no shortcut.

Hope this information clarifies the situation
