Created attachment 490796 [details] Noisy boot scroll for X4600 M2 with Emulex FC HBA Description of problem: Since updating to kernel 2.6.18-238.5.1.el5 boots have become extremely noisy with regard to dealing with the ghost path of an ready/ghost pair of connections to a Sun 2540 disk array. This happens on all of our Sun X4600 M2 servers with both QLogic and Emulex FC HBAs. Example output of "multipath -ll": datavol (3600a0b800038b3e500000224477df1d2) dm-2 SUN,LCSM100_F [size=1.5T][features=1 queue_if_no_path][hwhandler=1 rdac][rw] \_ round-robin 0 [prio=100][active] \_ 2:0:0:0 sdc 8:32 [active][ready] \_ round-robin 0 [prio=0][enabled] \_ 1:0:0:0 sdb 8:16 [active][ghost] Version-Release number of selected component (if applicable): kernel-2.6.18-238.5.1.el5 How reproducible: Every boot. Steps to Reproduce: 1. Move from kernel 2.6.18-194.32.1.el5 to 2.6.18-238.5.1.el5 2. Reboot 3. Watch scroll Actual results: Extremely noisy boot when checking ghost path. Attempt to use various incorrect SCSI drivers for ghost path. Error on attempting to insmod dm-multipath as it's already loaded, yet still give "Buffer I/O error" when attempting to access said ghost path. Various worrying "FLOGI" failures. Expected results: No noise. Not only should it not be seemingly trying a succession of drivers for the HBA, it should also have loaded dm-multipath early enough that the "Buffer I/O error on device sdb" should also not be happening. Appearance of "FLOGI" messages equally disturbing.
