Hello to all,
what is the command in Solaris/Unix which I can use to determine how many hard disks exist in the system?
I have tried with different command such as df -lk and similar but cannot know for sure how many actual disks are installed.
Commands like # fdisk -l | grep Disk and # lshw -short -C disk doesn't work in Solaris.
Thank you.
You are maybe using pools... type zpool list to see...
Unfortunately, this is not it. I receive "no pools" result.
Try
format
or
cfgadm
yeah, after format just count the number of disk? There is actually already a count, however it starts with zero. So just add +1 to what ever number is present in format.
Yes...
How about?
ls /dev/[sh]d*[!0-9]
If you just need the number:
ls /dev/[sh]d*[!0-9]|wc -l
Hope ths helps
/dev/hd* /dev/sd* is a very linux-specific answer. Not all systems use those device names. For that matter, even Linux doesn't use those all the time -- some RAID cards will give funny names. In Linux, you can check for all block devices in /sys/class/block, and filter out irrelevant ones by looking deeper in /sys/class/block/[device].
Any good answer will have to be system-specific, because this is a management question, not a system environment one.
This is a Solaris box but is it SPARC or x86?
If SPARC does it have a System Controller? (SC> prompt)
This will give you the count and some more information about each disk on a Solaris machine:
iostat -En|awk '/^c[0-9]/{printf("\n%3d : ",++d)}{gsub(" *"," ");gsub("[A-Za-z ][A-Za-z ]*: 0 ","");printf("%s ",$0)}END{printf("\n")}'
you should be able to use
iostat -En
Thank you all for the feedback. However this last command didn't help me.
In fact I was trying this command: df -lk, and when execute this command I get this results:
File system 1024-blocks Used Available Capacitiy Mounted on
/dev/dsk/c0t0d0s0 ............................................................................... /
/devices ................................................................................................ /devices
ctfs .........................................................................................................../system/contract

/dev/dsk/c0t1d0s0 ....................................................................................../inglog
/dev/dsk/c0t0d0s5......................................................................................
/dev/dsk/c0t0d0s4......................................................................................
/dev/dsk/c0t1d0s1
So how can I recognize from this output how many disks there are in the system?
Thank you
There are at least two disks on your system, c0t0d0 and c0t1d0.
Please explain why
iostat -En|awk '/^c[0-9]/{printf("\n%3d : ",++d)}{gsub(" *"," ");gsub("[A-Za-z ][A-Za-z ]*: 0 ","");printf("%s ",$0)}END{printf("\n")}'
doesn't answer your question ?
Yes, it does answer my question. Sorry, I was refering to /dev/hd* /dev/sd* command.
iostat -En works perfectly. Thank you.
BTW, is c0t0d0 and c0t1d0 this number tx.... indicator how many disks there is in the system?
Not really. There is a controller number cx, a SCSI target number ty and a disk number dz. Each different combination of x,y and z denote a different disk.
