SATA RAID Question
|
|
| Henry Newman 2005-05-07, 5:46 pm |
| For low end RAID controllers like the Adaptec 1420 and 1210, and LSI
Logic MegaRAID SATA line:
If someone is running RAID-1 can you remove a drive and hook directly
to another SATA controller or do these controllers write something in
the low cylinders that prevent them from being used by another,
non-RAID controller from a different manufacturer. Any pointers to
more detailed information appreciated.
Thanks

| Try low-level format in this case, in FreeBSD it is "camcontrol format
da0". In Windows, you can download the open-source "scu" tool, which IIRC also
exists in Linux.

| This does not really answer the original question. What I want to
know is can I remove a drive from an Adaptec or MegaRAID and put into
another PC and use the drive and the data (not reformat) or so the
controller write something in to low cylinders that prevents it being
used by another controller.
Thanks

| In general I have found that moving RAID sets from one brand of RAID
controller to another is unlikely to work. Many controllers write the
information about the RAID set on to the drives.

The metadata is vendor/product unique. So, the answer is no.

| For LSI controllers, you can probably move the drive to a standard
controller and access the data. The controller's disk configuratiyon is
stored at the end of the disk. For a RAID 1 volume, the MBR won't include
the "configuration" area, so you *should* be OK.
