Shadowing a Volume

Configuring a Shadow-Copy Rule (Source Switch)

15-20 CLI Storage-Management Guide

For example, the following command sequence disables pruning for the shadow-copy

rule, DRrule:

bstnA6k(gbl)# namespace wwmed

bstnA6k(gbl-ns[wwmed])# volume /acct

bstnA6k(gbl-ns-vol[wwmed~/acct])# shadow-copy-rule DRrule

bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRrule])# no prune-target

bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRrule])# ...

Enabling Pruning

Target-pruning is enabled by default, to ensure that the source and shadow volumes

match after the first shadow copy. From gbl-ns-vol-shdwcp mode, use the

prune-target command to re instate this default:

prune-target

For example, the following command sequence enables pruning of shadow volume

target volumes for the ‘bkup’ rule.

prtlndA1k(gbl)# namespace testns

prtlndA1k(gbl-ns[testns])# volume /users

prtlndA1k(gbl-ns-vol[testns~/users])# shadow-copy-rule bkup

prtlndA1k(gbl-ns-vol-shdwcp[testns~/users~bkup])# prune-target

prtlndA1k(gbl-ns-vol-shdwcp[testns~/users~bkup])# ...

Copying Only Directories with Changed Files (optional)

By default, a shadow-copy rule copies all directories from the source volume, whether

or not they have files from the source fileset. This can result in empty directories in

the shadow volume. Use the

directory-copy as-needed command to copy only the

directories that contain at least one file:

directory-copy as-needed

For example, the following command sequence stops the “DRrule” from copying

empty directories:

bstnA6k(gbl)# namespace wwmed

bstnA6k(gbl-ns[wwmed])# volume /acct

bstnA6k(gbl-ns-vol[wwmed~/acct])# shadow-copy-rule DRrule

bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRrule])# directory-copy as-needed
