Migrate/Expand a RAID 1 to RAID 5 on a P410i

[PontoPR]

Hi all,

I'm trying to expand the capacity of a RAID 1, by adding a new disk and converting it to RAID 5.

Note: I'm using a 256MB cache.

Using the HP Array Configuration Utility, when I try to do this operation it reports:

=> show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 5001438009DE2250)

   array A (SAS, Unused Space: 0 MB)


      logicaldrive 1 (136.7 GB, RAID 1, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 146 GB, OK)
      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 146 GB, OK)

   array B (SAS, Unused Space: 0 MB)

   array C (SAS, Unused Space: 0 MB)


      logicaldrive 3 (136.7 GB, RAID 0, OK)

      physicaldrive 2I:1:8 (port 2I:box 1:bay 8, SAS, 146 GB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 5001438009DE225F)

=> array A add drives=1I:1:3

Error: This operation is not supported with the current configuration. Use the
       "show" command on devices to show additional details about the
       configuration.

Here is the configuration that I have:

Any help? What am I missing?

Hi André Silva,

Were you able to migrate the Raid 1 to Raid 5 by adding an additional Hard drive and upgrading 512 BBWC?

Please update us on the status.

thanks,

Aftab

Good day. I have a similar sotuation. I wanted to migrate the RAID1 to RAID5. I have replaced the 256MB Cache with 512MB Cache. But there is still NO migrataion button in ACU (it is possible to add a new hard drive to the existing RAID1 array but not possible to migrate to RAID5)! Why? Screenshots attached. Thanks.

HI, I read your post. Is it possible to add a drive and expand raid 1 without deleting the data?
