Hi all,
We've got the following problem :
We have 2 ds6800 configured with san switches and fibrechannel, on AIX we've used mpio for connection to the disks.We've setup mirroring within AIX ( 2 copies for every LV , each residing on a different DS ).We've come across the following phenomenon :
When one of the mirrors is offline, normally the machine should nicely continue working on the other, but instead all operations performed to the disks just hang, get timed out,lsvg gives a message that it has been locked, some vg's even get corrupted . Anyone experienced similar behaviour with DS6800 or ESS.We've got a feeling that it could be the mpio, but for now we haven't got a clue how to solve it, and this weekend the machine was planned to be taken into production...
thx in advance
regards
