Hi,

I am taking dump of few datasets and I am facing this message.

ADR411W (001)-DTDSC(04), DATA SET HSM.OCDS IN CATALOG CATALOG.VSYST01 ON VOLUME SYSN01 WAS NOT SERIALIZED ON REQUEST

I went through the manuals and as far as i understood problem is related to the VTOC of the dataset.

Could anyone please suggest how to resolve this problem. Do I need to uncatalog and then catalog the dataset HSM.OCDS on the new volume?

HSM control datasets should not really be touched by external backup / dumps.

They should only be processed by HSM iteslf with the use of HSM's internal CDS backup facility. This is very important as it keeps the HSM log in sync with the CDS backups.

Using external methods to backup these datasets can cause irreprible harm.

the message is probably the consequence of using the TOLERATE(ENQFAILURE) parameter

anyhow I stand by expat in his recomendations..
unless You are undergoing some kind of dataset redistribution/reallocation
( but in this case HSM should not be up )

Yes I used TOL(ENQF) parameter because of which the datasets were not dumped.

We will plan to bring down HSM to move a head.

Thanks a lot for you inputs.

Are you trying to MOVE the CDS ?

If so, why is HSM still up.

Stop all HSM backup / migrate / restore / recall functions
Perform the HSM internal CDS backup
Bring HSM down
Move the dataset - I have always used REPRO to newname and then rename
Bring HSM up again

Yes we are trying to move CDS too.

HSM cannot be brought down as is used by production continuously.

Is there any way we take dump of HSM files when HSM is up?

To move a CDS in use by HSM you must bring down HSM to preserve the integrity of the CDS.

Think about it. You copy the CDS, HSM quite happily performs its functions during this copy using the original CDS, and you then flip the catalog to point to a CDS that does not have the updates recently performed.

If HSM needs to take a hit to perform this task, that is the end of the matter.

Then I would seriously take a deep long look at your storage management policies.

You can plan a maintenance outage (even though undesirable) or you may have to deal with an unplanned crisis - which may cause an even longer downtime and/or loss of data.

Most management really resents crisis. . . .
