Determine Disk Total

[Mushy_1]

Hi!

We are using Tru64 Unix to house one of our applications. Also, we have a Storage Area Network that handles the disk requirements of the system. So, we allocated part of the SAN to this Unix server. As i use the df -k command, i get to see all the file systems but then the total size of the filesystems does not equal size that i allocated from SAN. Could there be any other part that i do not see in 'df -k' command?

Hi,

it depends on. ADVFS uses some space for internals. Is the difference big? Sometimes there a files hidden behind a mount point.

greetings,

Hi! im not sure if i am doin the right computation. But here's the output of the df -k command. Please help me determine the total. Thanks!

That will be around 36GB.
Is that the LUN size you have allocated?

Hi,

to it is roughly 290-300GB

Hi again,

that was used only.
Total is roughly 373GB

thanks so much for the help. so i am right in computing the total disk space approx 360GB. However, disk allocated to the server from SAN is 741GB. where could the other be?

Please post the full output (Better if you attach a txt file) of the following commands:

hwmgr v d
hwmgr show scsi
ls /etc/fdmns/*
df -k
swapon -s
showfdmn

Where is the name of every domain listed in the output of df.

Mushy,

this is roughly half of your size. Can it be that you have to divide it by 2 for raid 1?

Hi!

Again, thanks for responding to my inquiries. I got all the data that you asked me to save. Can you please look at it? We are using RAID 5. Yes, you are right that the total size that we got is half of what i expect. Does it have something to do with unmounted file systems? I really appreciate your help.. Thanks again!
