Ok, maybe im at a loss here in the way my brain is viewing this we have a box, its got 2 nodes in the chassis, and 32 sata drives attached to a SATA/SAS backplane via 4 (2 per node) LSI MPT SAS2 cards should i not logically be seeing 4 controllers X #drive count ?? camcontrol devlist shows 32 devices, daX,passX and sesX,passX <SEAGATE ST33000650SS 0004> at scbus0 target 9 lun 0 (da0,pass0) <STORBRICK-3 1400> at scbus0 target 10 lun 0 (ses0,pass1) <SEAGATE ST33000650SS 0004> at scbus0 target 11 lun 0 (da1,pass2) <STORBRICK-1 1400> at scbus0 target 12 lun 0 (ses1,pass3) <SEAGATE ST33000650SS 0004> at scbus0 target 13 lun 0 (da2,pass4) <STORBRICK-2 1400> at scbus0 target 14 lun 0 (ses2,pass5) <SEAGATE ST33000650SS 0004> at scbus0 target 15 lun 0 (da3,pass6) <STORBRICK-4 1400> at scbus0 target 16 lun 0 (ses3,pass7) <SEAGATE ST33000650SS 0004> at scbus0 target 17 lun 0 (da4,pass8) <STORBRICK-6 1400> at scbus0 target 18 lun 0 (ses4,pass9) <SEAGATE ST33000650SS 0004> at scbus0 target 19 lun 0 (da5,pass10) <STORBRICK-0 1400> at scbus0 target 20 lun 0 (ses5,pass11) <SEAGATE ST33000650SS 0004> at scbus0 target 21 lun 0 (da6,pass12) <STORBRICK-7 1400> at scbus0 target 22 lun 0 (ses6,pass13) <SEAGATE ST33000650SS 0004> at scbus0 target 23 lun 0 (da7,pass14) <STORBRICK-5 1400> at scbus0 target 24 lun 0 (ses7,pass15) <SEAGATE ST9300605SS 0004> at scbus1 target 0 lun 0 (da8,pass16) <SEAGATE ST9300605SS 0004> at scbus1 target 1 lun 0 (da9,pass17) <STORBRICK-3 1400> at scbus8 target 10 lun 0 (ses8,pass19) <SEAGATE ST33000650SS 0004> at scbus8 target 11 lun 0 (da11,pass20) <STORBRICK-1 1400> at scbus8 target 12 lun 0 (ses9,pass21) <SEAGATE ST33000650SS 0004> at scbus8 target 13 lun 0 (da12,pass22) <STORBRICK-2 1400> at scbus8 target 14 lun 0 (ses10,pass23) <SEAGATE ST33000650SS 0004> at scbus8 target 15 lun 0 (da13,pass24) <STORBRICK-4 1400> at scbus8 target 16 lun 0 (ses11,pass25) <SEAGATE ST33000650SS 0004> at scbus8 target 17 lun 0 (da14,pass26) <STORBRICK-6 1400> at scbus8 target 18 lun 0 (ses12,pass27) <SEAGATE ST33000650SS 0004> at scbus8 target 19 lun 0 (da15,pass28) <STORBRICK-0 1400> at scbus8 target 20 lun 0 (ses13,pass29) <SEAGATE ST33000650SS 0004> at scbus8 target 21 lun 0 (da16,pass30) <STORBRICK-7 1400> at scbus8 target 22 lun 0 (ses14,pass31) <SEAGATE ST33000650SS 0004> at scbus8 target 23 lun 0 (da17,pass32) <STORBRICK-5 1400> at scbus8 target 24 lun 0 (ses15,pass33) <USB 2.0 Flash Drive 8.07> at scbus9 target 0 lun 0 (da18,pass34) we would like to create a zpool from all the devices, that in theory if nodeA failed then nodeB could force import the pool, nodeA and NodeB are attached through dual LSI controllers, to the SATA/SAS backplane. but i cant seem to create a zpool from sesX or passX devices, i can however create a 16 drive zp0ol on either node, from any daX device. what did i miss? ive looked at gmirror, and also ses documents. Any insight is appreciated, thanks in advance.
