*** Bug 168395 has been marked as a duplicate of this bug. *** This creates a problem for disks slated to be used in the native multipath failover product. FYI My testing on another 2.6 based Enterprise Server Linux showed that it can correctly identify labeled multipath LUNS. This testing also showed that when 2 LUNS were given the same label it was able to correctly fail to mount the device with the duplicate label error. My hope in bring this to light (adding this comment) is that a fix for the problem might be available in an up-stream version. I thought that if RedHat were aware of a potential fix for the problem it might help resolve this. Arthur - currently, Red Hat is not supporting booting from the SAN with multiple paths. Are you using PowerPath or the device-mapper-multipath? Are you using LVM2 in conjunction with the multipath functionality? Thanks. Heather I was attempting to use the native failover product. I got as far a installing the OS on a network drive and rebooting. the /boot partition did not mount because it saw multiple copies of the disk label. My plan was to test the device-mapper-multipath bundled with Update 2. Also LVM is configured during the initial install for the / partition. When is boot from SAN targeted for support in RHEL4 using MPIO? At this point in time, I am not sure if or when SAN boot is going to be supported when using the device-mapper MPIO. Alasdair - do you have any insight into this? Thanks. We have no plans to add multipath fixes to anaconda for RHEL4. That support first appeared in RHEL5.1 (or .2) and was very complicated to get right. It's too much work to backport into RHEL4 without the potential for major destabilization. |
