[dm-devel] Losing paths

Hi,
We had similar problem last year using sles9 and SVC 4.2.0.2,  as you describe: adding/deleting a LUN causes brief path failures for the host's remaining, unaffected LUNs.

We were using tur checker and it turned out that while adding/deleting a LUN (and some other admin tasks) the SVC does not respond well to test-unit-ready tur requests; but it responds perfectly well to normal read commands. I opened IBM PMR 43118 on that if you want to ask the SVC folks about it.  

Workaround for us was to use readsector0 instead of  tur as multipath path checker. 
 
Recent post here (see July 8, 2008)  said multipath-tools is deprecating readsector0, and to use directio as path checker, but directio was said to be much slower than tur, implying tur was better replacement than directio for readsector0. 

Not sure what deprecating readsector0 means for us SVC users.  

regards,
John

Subject: [dm-devel] Losing paths

To all,

Is it normal DM behavior that we are (temporary) losing paths from 'unaffected' LUN's when we unmap a SAN LUN from the storage side.
We are using an IBM SVC (4.2.1) and RH AS 4.6. We are using the multipath.conf file supplied by IBM for the SVC.

It's normal that you loose the paths of the LUN which you unmap (4 paths in our case), but why we are also losing paths from 'unaffected' LUN's.
Unmapping a LUN is not a normal storage admin action but could happen accidentally.
We also see the same behavior when we give a new LUN to the Linux server. The minute we map the LUN, paths from other LUN's are temporarily disappearing.

We tried several settings/HBA firmware etc. but can not eliminate this behavior of DM.
