[Ilugc] Need Help on Storage

[Yuvaraj]

I have a slight issue on our server.

I have added some extra storage on an Infortrend Raid – the disks show up
on boot up and is assigned by the system. Now when in LVM manager the disks
don't show up. I have included the part of the boot message so you can see
the disk assignment.



Can you let me know why they don't show up in LVM Manager in RHEL5.

The boot message is not available here.
snip here or use pastebin service to give the url.

give the output of the command 'fdisk -l' run as root.

Given this is a hardware raid controller, you probably noticed the disk
'showing up' on the raid controller utility menu just before the OS is
booted. correct?

Usually, with a hardware raid controller, you don't get to access to the
underlying disks*. You will instead see unified disk(s).

* unless you also have some kind of a specialized software (such as HP ACU
CLI) using which you can 'talk' to the raid controller to query various
things from it (such as the list of drives installed, their status, etc.,).
Some raid controllers do support 'direct disk' mode, but you have to check
with your RAID hardware's manual.
