RedHat 3.4 with ServiceGuard and EVA3000
# pvcreate -v -f /dev/sda
pvcreate -- locking logical volume manager
pvcreate -- checking physical volume name "/dev/sda"
pvcreate -- getting physical volume size
pvcreate -- checking maximum physical volume size
pvcreate -- checking partition type
pvcreate -- invalid physical volume "/dev/sda"
What can I do to correct the this message.

Re: RedHat 3.4 with ServiceGuard and EVA3000
What options would I need to add with sdisk for /dev/sda?

Re: RedHat 3.4 with ServiceGuard and EVA3000
did you assign the "SUN" (or is that called "Solaris"? - I don't remember at the moment, sorry) operating system type to the Host entry?

Re: RedHat 3.4 with ServiceGuard and EVA3000
# mke2fs -v /dev/sda mke2fs 1.32 (09-Nov-2002) /dev/sda is entire device, not just one partition!
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)

Superblock backups stored on blocks:

Warning: could not read block 0: Attempt to read block from filesystem resulted in short read Writing inode tables: done Writing superblocks and filesystem accounting information: done
Does Linux create raw device files that would be assosciated with /dev/sda? Normally to do pvcreate (in HPUX) you would need to use the character device file. Is there anything like that for Linux RH?

Re: RedHat 3.4 with ServiceGuard and EVA3000
Once that is done then you run vgscan, then do the pvcreate.
what does fdisk -l reveal for these devices?

Re: RedHat 3.4 with ServiceGuard and EVA3000
# sfdisk -l /dev/sda
Disk /dev/sda: 261 cylinders, 255 heads, 63 sectors/track
read: Input/output error
sfdisk: read error on /dev/sda - cannot read sector 0
/dev/sda: unrecognized partition
How would I run the sfdisk command to mark the LUN with 8e for the linux type?

Re: RedHat 3.4 with ServiceGuard and EVA3000
lvm is different on Red Hat. You can create multiple volume groups on one disk for example. You can't boot Red Hat off an lvm parition.
Besides that, it would seem you have a problem with the disk /dev/sda
sfdisk -l /dev/sda
Does it show anything?

Re: RedHat 3.4 with ServiceGuard and EVA3000
Disk /dev/sda: 261 cylinders, 255 heads, 63 sectors/track
read: Input/output error
It seems hareware/LUN error . Could you create another LUN to have a try? Or delete this LUN and recreate.
