Adding new LUNs (easier) on Linux
Previously we ran Linux on HP servers with HP OEM’ed QLogic HBA’s. One nice thing about that was that the HP driver pack containted a couple of nice support scripts (namely hp_rescan) – We used the HP drivers because the driver in the kernel (earlier on at least) did not support multi-pathing. When we started using IBM xSeries servers we had the following configurations: SLES9 with QLogic drivers SLES10 with multipath RHEL4 with multipath RHEL5 with multipath The problem with all configurations is that none of them sported anything like hp_rescan....
