Checking free disks

[Jayraj]

Hello every one..

file system is 100%.. No PE's available to extend the filesystem. I used ioscan -funC disk to check weather any free disks available... But how to Identify which one is free disk from that output..

Thank u..

You would have to take the output from ioscan and check that against output from 'vgdisplay -v' which would show all of your VGs and what disks they use.

Now this is assuming that all your disks are managed by LVM. If you are using VxVM (Veritas Volume Manager) then you will need to use the appropriate tools to check your Veritas Disk Groups.

This also assumes that you don't have any disks being used as RAW storage by a database or some other application.

HI..

I have checked the the disks assigned to that volume group are full now... So Now I want to find out weather any free disks are attached to my server.. so I used ioscan -funC disk.. but how to find out which one is empty so that I can include that in present volume group..

You can go to SAM > Disk and File Systems.

If you go to Volume Groups, it shows how much space left for each Volume Group and if you try to create a new volume, it will tell you whether you have any empty disk left.
