Re: [dm-devel] Losing paths



Hi Guy,

Does the 'tur' checker take into account unit-attention issues (i.e. when the configuration of a SCSI device changes, the next command coming from an afected initiator (not necessarily to the same LU) should be failed with a 'check condition' error and a 'unit attention' sense code.

if the TUR checker sent a TUR right after the change and before another read/write command was sent - it will be failed, and then the question is, whether the lower-level driver retries the TUR command, or returns an error. any idea?

It does for SLES10 SP2. Upstream not; I'll have to send the
patches one day.

Cheers,

Hannes
