Nice... very nice..
But you can directly update volumes  using the following command:
Update vol VOLUMENAME access=READWRITE
                                        READONLY
                                        OFFSITE
                                        UNAVAILABLE
                                        DESTROYED

Thanks & Regards,

Subject: [ADSM-L] Need to perform simple restoration test from offsite tape

Hello,

I'm required to perform data restoration test from some offsite tapes. I have 
never done before this but
did some reading from internet.

Below is my understanding :

1) Check offsite tapes into library.

2) Update the status of OFFSITE to readonly. (I'm not sure about this, this 
appear as one of the step I
read in an article. I assume that this is to prevent accidental writes to the 
offsite tapes).

update vol * wherestgpool=offsitepoolname whereaccess=offsite
access=readonly


3) Update the status on onsite tapes to DESTROYED or UNAVAILABLE. I assume I 
can update invidivual volumes/tapes to unavailable

update vol * wherestgpool=onsitepoolname access=DESTROYED or UNAVAILABLE

(The article only mentioned DESTROYED. I saw the UNAVAILABLE option from
the command reference. I think I would use UNAVAILABLE as it sounds less 
harmful. I don't know what is the impact if I use
DESTROYED option as we will need to continue to use the onsite tapes after 
testing)

4) Restore data.

5) After restoration of data, update the onsite pool to readwrite and update 
the offsite pool to readwrite
(This step is not mention in the article I read, I assume this is the step to 
normalize things)

Is my understanding correct? Hope someone could help on this.

Thanks

Chan
