Re: DEDICATED DASD - How to backup?
The guests that the 2nd-level system is running are CMS users and applications. It seems logical to me that if a weekly backup was scheduled when the users are not online and working, the system could be quiesced and backups could be taken. This is what they did when the system was moved to our z10. They logged off all non-system users and did DDR backups. When we restored to our system, it came up without issue. -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Alan Altmark Sent: Monday, September 20, 2010 8:18 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: DEDICATED DASD - How to backup?

DEDICATED DASD - How to backup?
I have a guest OS running on 3380 DASD. All of the DASD is defined with DEDICATE statements to that guest only. I'm now trying to determine how to backup that guest. I have the CA VM:Backup (with HiDRO) product, but I'm told it probably won't work because the guest has no minidisks. We have a VTS here, so all the data will be written to virtual tape using the DFSMS/VM (RMS) and CA's VM:Tape. Does anyone have any suggestions? Thanks in advance, Dave Keeton
Re: DEDICATED DASD - How to backup?
Can the guest be shutdown to do a backup? If so, try defining a full pack minidisk on the dedicated drive and then use vm:backup to backup the minidisk. Does the guest OS have a backup utility?

Re: DEDICATED DASD - How to backup?
It was to create a clear separation from the rest of the system. I'm not saying it was the best solution, it was the most expedient. I can certainly change it. I can't use DDR though - the guest is using emulated 3380 and the rest of the DASD on the system is 3390. I can't DDR copy from dissimilar volumes.

As a stop gap you could change the DEDICATE's to MDISK with the DEVNO option. A minor variation would be to put all the MDISKs with DEVNO in a new placeholder userid and change the guests from DEDICATEs to LINKs. Having all the DEVNOs in one place may make administering them easier. YMMV. In either case, now they are MDISKs for HiDRO.

Re: DEDICATED DASD - How to backup?
I have a maintenance window of two days a month in which I COULD shutdown the guest, but it'll meet with resistance I'm sure. Will shutting it down to get the backups meet with any more resistance than the system not being able to run after a restore has been performed? What you suggest is backing up one running system from a 1st level system that has no idea of the filesystems on the 2nd level system. Sure, VM:Backup on the 1st level system knows about CMS files - as long as the minidisks are defined to the 1st level system. But that 2nd level system has it's own CP Directory which cannot tell VM:Backup where the 2nd level systems minidisks start and end, or even who owns the minidisks. So... at best you'll get full-pack physical backups from VM:Backup, or from any other product or tool. That's: read a DASD cylinder of bits, write a DASD cylinder's worth of bits to tape. No file-level restores, just whole cylinders. And consider also that the applications on that 2nd level system may be writing to several difference minidisks on different DASD. The VM:Backups will be inconsistent, since the minidisks will be backed up when the app is writing data at different times than the individual cylinder backups are made. That's why database products have their own backup tools - they can ensure a consistent backup. Is there any reason that the 2nd level system could not have VM:Backup installed on it to run its own backups? Yes, you'd have to attach tape drives during the backups, but that is do-able. And if you are using VM:Tape, that 2nd level system would need to have VM:Tape installed as well - again, that's do-able. And that would require any added licensing costs system the CA products are still running on the same physical CPUID. All that said... for many years we had the MVS sysprogs make FDR backups up the VM system DASD, while the VM system was up and running. At no point during any of the (perhaps) 15+ semi-annual D.R. tests were we unable to bring up the VM system once the MVS sysprogs had FDR-restored the VM DASD. After a few tests I grew more leery (see the database/multi-minidisk considerations above). So we ran extensive CMS filesystem utility checks on every single minidisk looking for filesystem errors. None were ever found. We eventually switched to running VM's own VM:Backup D.R. backups (after the MVS guys stopped running any more VM DASD backups w/o telling us - twice!).

I have a guest OS running on 3380 DASD. All of the DASD is defined with DEDICATE statements to that guest only. I'm now trying to determine how to backup that guest. I have the CA VM:Backup (with HiDRO) product, but I'm told it probably won't work because the guest has no minidisks. We have a VTS here, so all the data will be written to virtual tape using the DFSMS/VM (RMS) and CA's VM:Tape. Does anyone have any suggestions? Thanks in advance, Dave Keeton

The hope was to back it up daily. There's a total of 42 3380 volume currently. As to the OS, it's VM 3.1 ... yeah, old stuff! We're migrating a customer from their old mainframe. This is a temporary solution. You really don't want to back up that system while it's running. You need all the data to be consistent, and that only happens when the VM system is down. Even forgetting warm start/checkpoint data, remember that the guests it is running also have data on minidisks that needs to be consistent.
