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? (You didn't mention what the OS of the guest is). From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of KEETON Dave * SDC Sent: Monday, September 20, 2010 4:48 PM To: [email protected] Subject: 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
