However, we've never had enough interest to warrant the work needed to get it up on 2.6. In general, there's very little interest in it anymore. Re: LVM on FC The LVM on FC scsi disks should be normal. The more interesting part is the boot part. Boot support means getting the expansion rom driver configured properly (whether that be BIOS, EFI, or OpenBoot). If you go to the Emulex support/download page, and look for firmware for your adapter, there is documentation on the setting boot devices, etc. You will need to be careful that the disk is either used on its own or as a mirror, it can't be used as a raid set. Further boot specifics should defer to grub (or your favorite boot loader) and LVM. Outside the expansion rom driver setup, the fact that it's FC should not matter, and it should look like a normal scsi disk. And now the bad news... the LP8000 is rather old, it may be EOL'd, so you may not find the latest boot firmware, and you would be stuck with whatever is on the adapter, or find a newer one. -- james s Scott Edwards wrote: > Two things I'm trying to solve with my fc hardware.
