Shadowing a Volume
Configuring a Shadow-Copy Rule (Source Switch)
15-36 CLI Storage-Management Guide
Copying the Source Volume to Multiple Targets
To copy a source volume to more than one target, create a separate shadow-copy rule
for each target. Each shadow-copy rule can operate on its own schedule, or they can
all use the same schedule. For example, the following command sequence sets up a
second shadow-copy rule for the “wwmed~/acct” volume, which goes to a different
target switch using the same schedule:
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# shadow-copy-rule DRbkup
This will create a new policy object.
Create object 'DRbkup'? [yes/no] yes
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# from fileset worthSaving
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# target hostname provA5c
namespace wwmedBkup volume /acctBkup
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# schedule hourly
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# report DRbkup
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# enable
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRbkup])# ...
Removing the Shadow-Copy Rule
You can remove a shadow-copy rule to both disable it and delete its configuration.
Use the no form of the
shadow-copy-rule command to remove a shadow-copy rule:
no shadow-copy-rule name
where name (1-64 characters) identifies the rule to be removed.
For example, the following command sequence removes the shadow-copy rule,
“buHome,” from the “/home” volume:
bstnA6k(gbl)# namespace archives
bstnA6k(gbl-ns[archives])# volume /home
bstnA6k(gbl-ns-vol[archives~/home])# no shadow-copy-rule buHome
bstnA6k(gbl-ns-vol[archives~/home])# ...
