Hi Adrian, What logs have you checked.
The SanBoxes? Dmesg? Stmf service? Are you running snapshots? Dedup? Compression? IRQ sharing? echo ::interrupts | mdb -k -----Original Message----- From: Adrian Carpenter [mailto:ta...@wbic.cam.ac.uk] Sent: Friday, May 18, 2012 3:26 AM To: openindiana-discuss@openindiana.org Subject: [OpenIndiana-discuss] COMSTAR qlt dropping link and resetting We are using one port of each of a pair of Qlogic 2562 cards to act as a FC target for our Xen environment, we are running oi_151a4. The other port on each card is used as an initiator to attach to some FC storage(Nexsan). We use two Qlogic SanBoxes configured so that the Xen hypervisors have a redundant path to the FC target which provides a Storage Repository from a ZVOL. Everything works really well as expected with good throughput, but randomly once every couple of days simultaneously BOTH FC targets on the Openindiana box reset their FC connections - this of course causes real problem in Xen environment and is not help by having redundant multipaths. We are at a bit of a loss, does anyone have any suggestions?
