device file

Kwhite_1 — Tue, 07 Apr 2009 15:20:16 GMT

people I am on hp-ux 11.31 and using xp 12000 stprage. Is there a script or an easy way to link the devices from the xpinfo output to the ioscan controller devices without doing an

ioscan -m dsf /dev/rdisk/disk29
Persistent DSF Legacy DSF(s)
========================================
/dev/rdisk/disk29 /dev/rdsk/c11t0d7
/dev/rdsk/c8t0d7

As I have like a 400 devices under vxvm

Well....there are numerous ways to display/extract device names, but the simple fact is that you'll have to construct a loop in your script to process them all.

I'd probably set up a sed command keyed on null lines i. e. when a blank line comes up it's a new record. Process from there....

HTH,
Jeff

hi,

what information do you need exactly?
you could try 'xpinfo -d', or try this:

#!/usr/bin/ksh

xpinfo -i | awk '/rdsk/ {print $8"\t"$6"\t"$1}' | sed 's/\/dev\/rdsk\///' > xpinfo.tmp

ioscan -fnC disk > ioscan
paste -s -d"\t\n" ioscan.tmp > ioscan.tmp
rm ioscan

while read box lun dev;do grep "${dev}" ioscan.tmp ;done < xpinfo.tmp

rm xpinfo.tmp ioscan.tmp

# but it depends on the version of xpinfo, you could modify the first awk line

a sample output for the above script:

sorry, the last while loop should be:

while read box lun dev;do printf "%-15s %-8s" ${box} ${lun};grep "${dev}" ioscan.tmp ;done < xpinfo.tmp

#this will map the xpinfo lines to the ioscan ones, one line per disk

Hi Kwhite,

U can use

diff-used to compare text files

cmp-for comparing binary files

dircmp-used to compare two directories

cksum is much better than diff or cmp is the. It does a CRC checksum on the files. If they match, you are absolutely assured that the files are identical in content.
(Eg : if file1 and file2 are identical)

# cksum file1 file2
=> will return similar output in the 1st and 2nd field.

If by 'hidden' files, you mean do cp -pR * copy files that begin with '.' then no it does not but that is really determined by the arguments passed into the command from the shell.

Victor,

That did not work , I am attaching my xpinfo and ioscan, if you can attach the script that would be great.

xpinfo -il

are you sure you have '/dev/rdisk' in your xpinfo output?

Re: device file

Viktor Balogh — Sat, 11 Apr 2009 05:58:02 GMT

oooh, sorry. you must be using 11i v3, and in your ioscan output there are legacy DSFs. There's a -N switch for ioscan to showing with the new DSFs.

Re: device file

Viktor Balogh — Sat, 11 Apr 2009 06:10:00 GMT

ok, you can try this:

#!/usr/bin/ksh

xpinfo -il | awk '/rdisk/ {print $8"\t"$6"\t\t"$1}' | sed 's/\/dev\/rdisk\///' > xpinfo.tmp
ioscan -fnNCdisk | grep -v -e "^Class" -e "=" | sed 's/^disk/#disk/' | xargs | tr "#" "\n" > ioscan.tmp

while read box lun dev;do grep "/dev/disk/${dev} " ioscan.tmp ;done < xpinfo.tmp

rm xpinfo.tmp ioscan.tmp

#altough it is not so easy for me because #currently I don't have access to a 11iv3...
#plz report back if it helped

Thanks for all the efforts victor. The script gives output some what like this but still does not show the legacy devices like c3t0d1.
