RE: [PATCH] Midlayer initiated START_UNIT

["Sachin Mhatre \(smhatre\)" <smhatre@cisco.com>]

Has this patch been included in the linux 2.6.X kernel? This patch would
also help the iscsi LLDD as it is also facing the same START_UNIT
problem.
I would really appreciate any help on this matter.

Thanks,
Sachin

James,

This is a patch to issue a START_UNIT command from the midlayer error
handler. The ipr driver, which is currently out for review needs this to
function properly. Any time the adapter gets reset, the disk array
resources under the ipr adapter require another START_UNIT command. This
causes problems with the current error handling and these devices get
taken offline when this occurs.

This was being handled by the ipr driver itself, but Christoph did not
like seeing a LLDD issuing commands to devices, hence the patch.

Patch is against 2.6.2-rc2.

Thanks
