Hi Yury, thanks for Your hints, I had the same problem an figured it out now. >> - is it true that I need a hardware-specific handler for arrays running >> with active/passive controllers (like the Sun StorageTek 6140) to >> get the the LUN trespassing working? > > It's true only for non-AVT mode (set host type to Linux to turn AVT mode on) at least for the 6140 this is not correct. It sets the mode to RDAC for the Sun-RDAC-Driver ( http://www.sun.com/download/products.xml?id=44d12115 ). You have to choose 'Solaris (with Veritas DMP or other)' (named SOLAVT in the CLI) to enable AVT. >> - did someone get the Sun StorageTek 6140 configured for dm-multipath? >> (so that the LUN trespassing works) > > It should work as it does for other boxes with LSILogic controllers. > > path_grouping_policy group_by_prio > path_checker tur > prio_callout "/sbin/mpath_prio_tpc /dev/%n" Correct, with this setup and AVT enabled LUN trespassing works as designed: multipathd> show maps topo reload: Raid5_for_IMAP-Volume (3600a0b800026851e000014e245bf1906) dm-0 SUN,CSM200_R [size=1.4T][features=0][hwhandler=0] \_ round-robin 0 [prio=12][active] \_ 7:0:2:1 sdah 66:16 [active][ready] \_ 6:0:0:1 sdd 8:48 [active][ready] \_ round-robin 0 [prio=2][enabled] \_ 6:0:2:1 sdn 8:208 [active][ready] \_ 7:0:0:1 sdx 65:112 [active][ready] and after failure of preferred controller: multipathd> show maps topo reload: Raid5_for_IMAP-Volume (3600a0b800026851e000014e245bf1906) dm-0 SUN,CSM200_R [size=1.4T][features=0][hwhandler=0] \_ round-robin 0 [prio=0][enabled] \_ 7:0:2:1 sdah 66:16 [failed][faulty] \_ 6:0:0:1 sdd 8:48 [failed][faulty] \_ round-robin 0 [prio=6][active] \_ 6:0:2:1 sdn 8:208 [active][ready] \_ 7:0:0:1 sdx 65:112 [active][ready] Great software!
