Example 20-14 rmpprcpath command
dscli> rmpprcpath -dev IBM.1750-13AAGXA -remotedev IBM.1750-13AAVCA 16:16
Date/Time: June 12, 2005 5:58:25 AM CDT IBM DSCLI Version: 5.0.3.110 DS: IBM.1750-13AAGXA
CMUC00152W rmpprcpath: Are you sure you want to remove the Remote Mirror and Copy path
16:16:? [y/n]:y
CMUC00150I rmpprcpath: Remote Mirror and Copy path 16:16 successfully removed.
You can suppress the CMUC00152W confirmation message by adding the -quiet parameter to
the command.
20.4.2 Manage Global Copy pairs
You can use the following commands to establish and manage Global Copy pairs.
failbackpprc
You can use the failbackpprc command against any Global Copy source volume that is in a
suspended state. The command copies the required data from the source volume to the
target volume in order to resume mirroring, as shown in Example 20-15. The command is
usually used after a
failoverpprc command has been given to restart mirroring either in the
reverse direction (recovery site-to-production site) or original direction (production
site-to-recovery site).
Example 20-15 failbackpprc command
dscli>failbackpprc -dev IBM.1750-13AAVCA -remotedev IBM.1750-13AAGXA 1600:1600
Date/Time: June 14, 2005 1:40:22 PM CDT IBM DSCLI Version: 5.0.3.110 DS: IBM.1750-13AAVCA
CMUC00197I failoverpprc: Remote Mirror and Copy pair 1610:1610 successfully failed back.
failoverpprc
You can use the failoverpprc command to change a target device into a (source) suspended
device while leaving the original source device in its current state; see Example 20-16.
Example 20-16 failoverpprc command
dscli> failoverpprc -dev IBM.1750-13AAVCA -type mmir -remotedev IBM.1750-13AAGXA 1610:1610
Date/Time: June 14, 2005 1:40:22 PM CDT IBM DSCLI Version: 5.0.3.110 DS: IBM.1750-13AAVCA
CMUC00196I failoverpprc: Remote Mirror and Copy pair 1610:1610 successfully reversed.
lspprc
The lspprc command shows you which volumes are in a Global Copy relationship; see
Example 20-17.
Example 20-17 lspprc command
dscli> lspprc -dev IBM.1750-13AAGXA -remotedev IBM.1750-13AAVCA -l 1600
