Steps for archiving virtual server disks
Before you begin: Shut down the Linux virtual server. You need to log onto
MAINT.
Perform these steps to archive virtual server disks:
1. Mount a scratch tape on a tape drive.
2. Attach the tape to MAINT. Type this command and press the Enter key:
attach rdev maint 181
where rdev is the real device address of the tape drive.
3. Link to the Linux virtual server disk you want to archive. From the command
line, type this command and press the Enter key:
link userid vdev1 vdev2 rr
where vdev1 is the virtual device address of a Linux minidisk and vdev2 is an
available virtual device address in MAINT’s configuration.
Example: To link MAINT to LINUX01’s 150 minidisk, issue this command:
link linux01 150 950 rr
4. From the CMS command line, type the DDR command and press the Enter key:
ddr
z/VM DASD DUMP/RESTORE PROGRAM
ENTER:
DDR prompts for control statements by issuing the ENTER: prompt.
5. At the ENTER: prompt, type this command and press the Enter key:
sysprint cons
6. Designate the disk from which DDR dumps the data. Type this command and
press
the Enter key:
input vdev2 dasd
where vdev2 is MAINT’s virtual device address (corresponding to the Linux
virtual server disk).
Example:
input 950 dasd
7. Designate the tape to which the data is to be dumped. Type this command and
press the Enter key:
output 181 tape scratch
8. Dump the disk to tape. Type this command and press the Enter key, then
respond to the prompts as shown:
dump all
HCPDDR711D VOLID READ IS LIN150
DO YOU WISH TO CONTINUE? RESPOND YES, NO OR REREAD:
yes ...
DUMPING LIN150 ...
ENTER:
9. To exit DDR, press the Enter key.
10. Repeat these steps for each virtual server disk you want to archive.
Continue with the next procedure.
