fdisk -l | grep disk   will list all the devices indiscriminate  of san or not

cd /etc/sysconfig
cat hwconf | more (has all hardware including san devices )



alternatively most hw vendors have tools to do this. EMC has inq which is a free tool downloadable from powerlink that will give device, lun, and label info.
Ignore my above post; for some reason I thought you were asking about redhat
for solaris format command will show all devices recognized

you could do a listing of /dev/c<#>t<#>d<#> to see what devices exist

Iostat -En (will give you device information regarding errors and vendor info)

Is EMC the only manufacturer of SAN for solaris? or are there other companies also. Is there any way to list the devices without downloadind the software? Using iostat how can I identify if the deivce is SAN of not? Thanks
No; there are many vendors of san storage. Hitachi, EMC, HP, IBM etc....

iostat -En (will show  vendor: XYZ) for example EMC or Clariion (also emc storage) is displayed for me.

Hi,

Thanks much for the info you provided. I have an environment which consists of multiple sun machines with different configurations. For some reason I  am asked to find the different types of storgage these machines are using. I can see couple of NAS easily when I do df -k. can you tell me how to identify and list san on each machine. All are running on solaris 8/9. They gave me the following command. Is this correct.

To list the SAN disks attached to the server:
iostat -E | awk '{ if ( ( $1 ~ /Vendor/ ) || ( $1 ~ /Size/ ) ) { printf $0; getline; print " -- " $0 }; }' | grep EMC | cut -d: -f6 | awk '{ print $1; }'

Which of the commands listed by you should I use to easily list and document san storage.on each of these machines? Thanks for being very helpful.

There are couple of machines we need to check.. I am just trying to get the procedure so that I can do it on all the machines...
It does not look like you are zoned for storage or your fiber card is not installed/drivers installed correctly. Make sure you are zoned with your storage admin. If you are then check to make sure that you have the correct fiber card drivers installed.
