Re: Disk Space

The normal, simple, way to see free disk space on Unix system is to issue 'df' (or bdf). But I don't think that is the answer you are looking for.

You question is too vague.

You need to learn to understand what your environment is and to describe it to us (in doing so you will probably answer your own question.

What does 'free' mean to you? Free to plunk files down on, free to create raw devices on?
Free to use as mirror disk in an LSM Plex?

Apparntly you 'see' 6 + 14 disks. Is that thardware you see? Does Tru64 see those drives?

hwmgr -show scsi?

Can you confirm we are talkign Tru64 on Alpha here? Which Alpha? Which Tru64?
Direct connect disks, individually presented, or a raid controller involved?

As asked in your other topic a few weeks back, how about a SHOW DEV on the console?

Hope this helps,

Re: Disk Space


What is your server environment and how you are using them.

First check the o/p of
hwmgr -v dev
#if all the 14 disks you cann't see run the command.
hwmgr -scan scsi

Then check how many disks are associated with which volume.
For that either you can run the command volprint -a , but it will give you so many confusing information.

Best way you find out all the created domains from /etc/fstab and then check associated volumes in each domain.
