How to view the device details ( not thru lsdev )

[Saravanan_6]

I want to view the device details ( eg. /dev/dsk/c16t1d0 )

By using the ioscan command, i can see the h/w path and other info of harddisk (/dev/dsk/c16t1d0) info. "ioscan -fnC disk"

I want to get the size and more info about that particular device...( /dev/dsk/c16t1d0 ).

Hope bdf and df -k wont be usable at this point. Because they will show the mounted vol's size ( /, /stand and lvol details).

Your help on this query is really appreciated.

Saravanan,

Use diskinfo /dev/cXtxDx command


Thanks,

Saravanan,

It is

diskinfo /dev/dsk/cXtXdX

Thanks,

Hi, you need to use character_devicefile with diskinfo:

diskinfo -v /dev/rdsk/c16t1d0

diskinfo -v /dev/rdsk/c44t0d0

Decoding the device file's characteristics starts with the lssf command which is more useful than lsdev and works for all device files such tapes, LAN cards, etc:

lssf /dev/rmt/*

For specific devices like disks, the diskinfo command is useful but for even more details, use cstm in batch mode as in:

echo "selclass qualifier all;info;wait;infolog"

hi Saravan

What Bill means is to run as root

#/root> echo "selclass qualifier ll;info;wait;infolog" | cstm | tee -a device.log

Then view device.log to see details.

You get a lot of output for all your whole system devices, disk, memory etc..
