Show disk ioscan in one line

[nz_1]

I am trying to get ioscan output for disk to be shown in one line.

So far I managed to do as below and include it in my script.

/usr/sbin/ioscan -fnCdisk |grep -v "Class" |/usr/bin/awk '{print $1" "$5" "$6" "$7" "$8" "$2" "$3" "$4"="}'|/usr/bin/sed -e :a -e '/sdisk=/N; s/sdisk=\n//; ta' |/usr/bin/awk '{print $1":"$2":"$3":"$4":"$5":"$6":"$7":"$8":"$9}' |grep -v "="

However, this wont work if there is no device file for the hardware.

Anyone has a better solution?
Thanks.

I use the attached.

Hi Nash:

When parsing the output of 'ioscan', using its '-F' option to produce colon-delimited fields eases the burden, particularly since missing fields are bounded by consecutive colons.

Hi James

Yes, -F option eases the burden but the the device files are still shown in a separate line.

Thanks.

Hi Pete

I will find myself an awk book.

Thanks.

p.s. Next task - combine vgdisplay, diskinfo and ioscan

I'm not sure what sort of output you desire.
But extracting the disks' paths is quite simple (piped to head for brevity)


$ /usr/sbin/ioscan -kFdsdisk|awk -F: '/CLAIMED/&&!/DVD|CD|SUBDISK/{print$11}'|head
0/0/1/1.2.0
0/0/2/0.0.0
0/0/2/0.2.0
0/10/0/0.107.21.19.0.0.0
0/10/0/0.107.21.19.0.0.1
0/10/0/0.107.21.19.0.0.2
0/10/0/0.107.21.19.0.0.3
0/10/0/0.107.21.19.0.0.4
0/10/0/0.107.21.19.0.0.5
0/10/0/0.107.21.19.0.0.6

Hi (again) Nash:

Output using awk uses a space as the default field separator. Hence:

# echo "1 2 3"|awk '{print $1" "$2" "$3}'

...is better written as:

# echo "1 2 3"|awk '{print $1,$2,$3}'

The comma indictes the interposition of the output separator.

You can change the default space separtor to any character you need by setting the OFS value like this:

# echo "1 2 3"|awk 'BEGIN{OFS="."};{print $1,$2,$3}'

...which produces the output:

1.2.3

A free, very nice tutorial to 'awk' can be found here:

If you need to convert the HW paths of the disks which are easily retreivable through ioscan's -F switch, as shown above, I am afraid you need to do a little scripting.
The controller or card No. (well the digits after the c in /dev/dsk/c?t?d?) can be taken from the instance Nos. that ext_bus class like

$ /usr/sbin/ioscan -kFCext_bus|awk -F: '$10~/fcparray|c720/{printf"%2d %s\n",$13,$11}'
0 0/0/1/0
1 0/0/1/1
2 0/0/2/0
3 0/0/2/1
11 0/10/0/0.107.21.19.0
4 0/12/0/0.117.6.19.0


The target and device or lun part is simply the last to period delimited digits of the disk paths' from my first posting.

But don't despair, the Solaris device tree even sucks more ;-)

Thank you all for the feedback. Here is my primitive script.
