Hi All, I have a working multipath on root, but some questions still unanswered. I'm hoping you can help me out ;) My setup details:Machine: IBM Blade Server HS21 with two Qlogic HBAs each connected to a FC switch with two active ports
Storage IBM DS4700 with two controllers OS: Fedora 7 DM packages: - device-mapper-1.02.17-7.fc7 - device-mapper-libs-1.02.17-7.fc7 - device-mapper-multipath-0.4.7-11.fc7 uname -r: 2.6.23.1-21.fc7 At the moment this is what I have: Output of multipath -ll: mpath0 () dm-0 IBM,1814 FAStT [size=4.0G][features=0][hwhandler=0] \_ round-robin 0 [prio=4][active] \_ 2:0:0:0 sda 8:0 [active][ready] \_ 2:0:1:0 sdb 8:16 [active][ready] \_ 3:0:0:0 sdc 8:32 [active][ready] \_ 3:0:1:0 sdd 8:48 [active][ready] Output of df -k: Filesystem 1K-blocks Used Available Use% Mounted on /dev/dm-2 3960348 1772124 1983800 48% / /dev/dm-1 101086 17593 78274 19% /boot tmpfs 1037416 0 1037416 0% /dev/shm Contents of /dev/mapper/: crw------- 1 root root 10, 63 2007-11-26 13:58 control brw-rw---- 1 root disk 253, 0 2007-11-26 13:58 mpath0 brw-rw---- 1 root disk 253, 1 2007-11-26 13:58 mpath0p1 brw-rw---- 1 root disk 253, 2 2007-11-26 13:58 mpath0p2 But this is what I really would like to have: Output of multipath -ll: SRV07_BOOT (3600a0b8000295d64000009304742b4c8) dm-0 IBM,1814 FAStT [size=4.0G][features=1 queue_if_no_path][hwhandler=0] \_ round-robin 0 [prio=0][enabled] \_ 2:0:0:0 sda 8:0 [active][ready] \_ 3:0:0:0 sdc 8:32 [active][ready] \_ round-robin 0 [prio=6][active] \_ 2:0:1:0 sdb 8:16 [active][ready] \_ 3:0:1:0 sdd 8:48 [active][ready]I can modify the table by modifying the init script in the initrd image and then booting with the modified initrd image but I don't know how to change the name from mpath0 to SRV07_BOOT.
Any help will be very appreciated!! Thank you, Pedro Faustino
