    What class are you talking about?  Are you wanting to do some sort of odmchange?  What is the solution that you found?  You sure it's not the PuAt database you're concerned about? Can you provide more information?

    Default values can be changed as follows:

    odmget -q              'values = "fail_over,round_robin" AND attribute = "algorithm" AND deflt = "fail_over"' PdAt|tee /var/tmp/odmtmp_$$_1 >>log.PdAt
    odmdelete -o  PdAt  -q 'values = "fail_over,round_robin" AND attribute = "algorithm" AND deflt = "fail_over"'
    sed 's/deflt = "fail_over"/deflt = "round_robin"/' </var/tmp/odmtmp_$$_1 >/var/tmp/odmtmp_$$_2
    odmadd /var/tmp/odmtmp_$$_2
     

    Additional AND clauses can be needed to change  only the targeted entries.

    As you can see, information is in PdAt and not CuAt.

    odmchange -o PdAt -q"uniquetype LIKE disk/fcp/MSYMM* and attribute=reserve_policy"  << EOF

    PdAt:
            deflt = "no_reserve"
    EOF
     

    odmchange -o PdAt -q"uniquetype LIKE PCM/friend/MSYMM* and attribute=algorithm"  << EOF

    PdAt:
            deflt = "round_robin"
    EOF
     

    But that's for EMC ;)

    Keep in mind changing PdAt like that is unsupported.

    One problem that can happen is a loss of customised device attributes when doing a migration or TL update due to the way some scripts used in the update process work. It can cause things to happen to your CuAt, which you don't want to happen to your CuAt.
