I use RHEL, it works very fine. Thanks.
I have another question. I tried with a normal server (without RAID controller) to simulate the storage and it cannot be recognized by multipath. Does it mean that I can't use a normal server (without RAID controller) to simulate the storage? Since the WWID used in multipath seems to be generated by the RAID controller. Thanks again.

What OS are you running? Steps for RHEL are: 1) Edit /etc/multipath.conf and comment out devnode_blacklist (RHEL4) or blacklist (RHEL5) entry. 2) Run "chkconfig multipathd on". 3) Reboot. 4) After reboot, /dev/mapper should be populated with mutipath block device entries. 5) You can run "multipath -l" to view the multipath status. Steps for SLES10 are similar: 1) Run "chkconfig boot.multipath on". 2) Run "chkconfig multipathd on". 3) Reboot. 4) After reboot, /dev/mapper should be populated with mutipath block device entries. 5) You can run "multipath -l" to view the multipath status. You use the /dev/mapper block devices, not /dev/sd* block devices.

I use 2 IB cables to connect the initiator and 1 IB cables to connect to the storage. I installed the OFED-1.2, enable the "SRP_LOAD=yes" and "SRPHA_ENABLE=yes" in openib.conf. After reboot, it discovers 2 targets /dev/sdbX and /dev/sdcX. However, I check the /var/log/srp_daemon.log, it shows: .. 26/05/07 17:42:57 : bad MAD status (110) from lid 257 26/05/07 17:43:30 : No response to inform info registration 26/05/07 17:43:30 : Fail to register to traps, maybe there is no opensm running on fabric .. But the opensm is running in both machines. I don't know whether it is normal, or should it only discover a single target? Now, my question is that if I mount the /dev/sdbX and write data to it, and then remove 1 of the initiator cable, how the /dev/sdcX will replace the /dev/sdbX so that I can continue to write the data? Do I need to configure some extra files? Thanks for reply. PN
