Removing ODM information of a logical volume

Sometimes situations occur where a logical volume is deleted, but the ODM is not up to date. E.g. when "lsvg -l" doesn't show you the logical volume, but the lslv command can still show information about the logical volume. Not good.

To resolve this issue, first try:

# synclvodm -v [volume group name]

If that doesn't work, try this: (in the example below logical volume hd7 is used). Save the ODM information of the logical volume:

# odmget -q name=hd7 CuDv | tee -a /tmp/CuDv.hd7.out
# odmget -q name=hd7 CuAt | tee -a /tmp/CuAt.hd7.out

If you mess things up, you can allways use the following command to restore the ODM information:

# odmadd /tmp/[filename]

Delete the ODM information of the logical volume:

# odmdelete -o CuDv -q name=hd7
# odmdelete -o CuAt -q name=hd7

Then, remove the device entry of the logical volume in the /dev directory (if present at all). 

Automatically e-mail error report entries

You can automatically forward all error report entries to your email. This next part describes how to do that. 

Create a file like this:

# cat /tmp/mailgeorge
errnotify:
  en_name="mailgeorge"
  en_persistenceflg=1
  en_method="errpt -a -l $1|mail -s \"errpt: $9\" abc@email.com"

Add this to the ODM:

# odmadd /tmp/mailgeorge

Now log an entry in the error report:

# errlogger "My coffee is cold"

You will see in the error report:

# errpt -a

Clear the error log again (because we logged a fake test-entry in the error report):
# errclear 0
Watch your email. You should receive the same error report entry in your email. 

By the way, you can delete this from the ODM like this:
# odmdelete -q 'en_name=mailgeorge' -o errnotify
