Finding installed raw disks and size

looseCannon · 10-28-2004, 08:04 AM

I've been given the task of running through a bunch of Solaris servers to see just how many hard drives and what sizes they are. As you can imagine this is a horrendously boring task and I want to automate it. Problem is, I'm really new to Solaris -- much more well versed in AIX and Linux.

Are there any sort of commands that are suitable for using in a script that would tell me what devices are installed?

On AIX you can issue the command 'lsdev -Cc disk' to get a list of disks the system knows about, so far I can't find anything like this in Solaris. I found the 'format' command, but that is interactive and not suitable for scripting.

Also, is there a command to display any fiber cards that are installed on the system?

I found how to get the internal disks, and it's scripting compatible. Here's what I used:

Code:

iostat -En|grep Size|egrep -v '1.49GB|<-1'|awk '{print $2}'

That returns only the hard drive sizes, and excludes the DVD drives.

Now for finding a command to show the FC adapters.

Guess I'll go ahead and answer all of my own questions. I managed to find the fiber cards by using this command:

Code:

prtconf|grep -c lpfc

In our enviroment we use LP fiber cards, so this works for us. Might not work for others.

The best thing about iostat and prtconf is neither one has to be run as root, so nothing has to be set up for sudo to be able to get this info if a normal user runs these commands.

Is the egrep -v '1.49GB|<-1' to exclude the DVDs ?

I tried on different systems and depending on if a DVD is mounted I have replies that would pass your filter:

Code:

c0t6d0          Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 
Vendor: TOSHIBA  Product: DVD-ROM SD-M1711 Revision: 1005 Serial No:  
Size: 0.00GB <0 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 
Illegal Request: 1 Predictive Failure Analysis: 0

or

Code:

c1t0d0           Soft Errors: 29 Hard Errors: 1 Transport Errors: 0 
Vendor: MATSHITA Product: UJDA720 DVD/CDRW Revision: 1.00 Serial No:

It worked on the initial system, but when I got to running that on a different server I found stuff like you did. Not sure how to keep the DVD's from showing up other than with common sense. Also, it won't keep out an SAN drives, if you have any.

So, this isn't a perfect solution, but at least it's not interactive and won't let you format a drive. Much safer than 'format'

So does anyone know a quick way to differentiate what disks are on a SAN and which are physically on the machine?
