Red Hat

hi all,

i have added new LUN to Redhat 5. i have already scanned LUN devices and it is confirmed that Kernel sees the newly added LUN's. i have used /proc/partitions and verified that my disks are there.
However, i cannot find my disk using fdisk -l command. I am not sure what did i do wrong. My ultimate plan is to add those disk in vxvm. i have also used vxdctl enable. which shows newly added disk but are marked with error.

i am not familiar with linux process of adding LUN. In Solaris i usually use devfsadm to make OS recognize the disk and after that i use format to label the disk and then add the disk under vxvm.

so, please guide me to step by step process of adding LUN and then adding those LUN in vxvm.

Thanks for your time and help

can you post output from cat /proc/partitions and fdisk -l ? You say you see the LUN in /proc/partitions, point out in the output the LUN you see in proc/partitions and missing from fdisk -l.

You have all the right steps, I think you may be misinterpreting the fdisk -l output. if it made to cat /proc/partitions, it should show in fdisk -l.

bash-3.2# cat /proc/partitions
130 32 70709760 sdfg
130 48 70709760 sdfh
130 64 70709760 sdfi "these are all the luns that were added"
130 80 70709760 sdfj
130 96 70709760 sdfk

I have lots of disks so can't copy all of them...but i searched for those disks...

bash-3.2# fdisk -l | grep /dev/sdf
