Hi Matt, On 02/19/10 02:53, Matthew Jacob wrote: > Just a total swag here, but reduce the openings via camcontrol to < 32, > or even < 16 Thanks for the suggestion. camcontrol doesn't seem able to futz with the mpt controller e.g.: root@server# camcontrol identify da0 -v (pass0:mpt0:0:2:0): ATAPI_IDENTIFY. ACB: a1 00 00 00 00 40 00 00 00 00 00 00 (pass0:mpt0:0:2:0): CAM status: CCB request was invalid However, there does appear to be a relevant sysctl: root@server# sysctl dev.mpt.0 dev.mpt.0.%desc: LSILogic SAS/SATA Adapter dev.mpt.0.%driver: mpt dev.mpt.0.%location: slot=3 function=0 dev.mpt.0.%pnpinfo: vendor=0x1000 device=0x0050 subvendor=0x1000 subdevice=0x3060 class=0x010000 dev.mpt.0.%parent: pci2 dev.mpt.0.debug: 3 dev.mpt.0.role: 1 dev.mpt.0.vol_member_wce: NC dev.mpt.0.vol_queue_depth: 128 dev.mpt.0.vol_resync_rate: 0 dev.mpt.0.nonoptimal_volumes: 0 Setting dev.mpt.0.vol_queue_depth=32, I can still trigger the "mpt0: mpt_cam_event: 0x16" messages by doing an svn up on the src tree. Same if I set depth to 16, so unfortunately it doesn't seem to do help in this case. Cheers, Lawrence
