hdisk mapping to a vSCSi Adapter

UNIX AIX
1

Hello,
I have a VIOS System and would like to do mapping some hdisks, hdisk160 until hdisk165 to a vSCSi Adapter. I try to do this in the oem_setup_env like the following:

for i in $(lspv | grep hdisk* | awk {'print $1'};
do
   mkdev -V $i -p vhost20
done

There where a mapping with hdisk16 but this is totally wrong. Can anybody give me some inspiration to realize this? Many thanks!

I don't know where to start

  1. your script wont run at all
  2. you want to map hdiskx-hdisky and not all hdisks on the system
  3. you don't grep this way (hdisk*) just hdisk is enough, and the * is substituted by the shell, grep wont even see it, grep uses regex
    when grep is used for hdisks for example, always use -w option, because hdisk16 would give you hdisk16 and hdisk165 for example
  4. mkvdev alias does not exist in oem_setup_env, it's an alias, you need to run /usr/ios/cli/ioscli mkvdev or set the alias, or run your script as padmin
  5. that's not the way awk works
 awk {'print $1'}
  1. don't use default mapping names, define your own, that's not a must, but makes you life much easier

couldn't test it, but this should work for you

for i in 0 1 2 3 4 5 
do
mkvdev -vdev hdisk16${i} -vadapter vhost20 -dev yourname_${i}
done

you may use "

for ((i=160;i<166;i++))

instead, but this will only work in ksh93

Thank you funksen but there is still a mistake, could you be so kindly and check the code?

$ for i in 0 1 2 3 4 5
> do
> mkvdev -vdev hdisk16${i} -vadapter vhost20
> done

The command's response was not recognized. This may or may not indicate a problem.

$ lsmap -vadapter vhost20

I've seen that message before when the hdisk is already mapped to another vhost. Try the following (as padmin) to check if hdisk165 is already mapped somewhere.

lsmap -all | grep -w hdisk165

I found the problem, the luns which I would like to map are flash copys. The flash copys where stopped so I started them an now the mapping works fine. Thanks a lot!
