Shadowing a Volume
Configuring a Shadow-Copy Rule (Source Switch)
15-14 CLI Storage-Management Guide
Including Identical Files in Reports
If files are identical on both the source and shadow volumes, the rule does not transfer
the file. By default, identical files are omitted from the shadow-copy reports. Use the
optional
list-identical flag to include these files in the report:
report prefix [verbose] list-identical
where prefix and [verbose] are explained above.
For example, the following command sets the “insurDR” rule to produce verbose
reports and include identical files:
bstnA6k(gbl)# namespace insur
bstnA6k(gbl-ns[insur])# volume /claims
bstnA6k(gbl-ns-vol[insur~/claims])# shadow-copy-rule insurDR
bstnA6k(gbl-ns-vol-shdwcp[insur~/claims~insurDR])# report insurDR verbose list-identical
bstnA6k(gbl-ns-vol-shdwcp[insur~/claims~insurDR])# ...
Deleting Empty Reports
By default, a shadow-copy rule creates a report every time it runs, even in cases where
no files are copied between volumes. To remove any empty-report files created this
way, use the optional
delete-empty flag at the end of the report command:
report prefix [verbose] [list-identical] delete-empty
where prefix, [verbose], and [list-identical] are explained above.
For example, the following command resets “DRrule” to delete any empty
shadow-copy reports:
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])# report DRetc delete-empty
bstnA6k(gbl-ns-vol-shdwcp[wwmed~/acct~DRrule])# ...
Disabling Reports
From gbl-ns-vol-shdwcp mode, use no report to stop generating shadow-copy reports
for the current rule:
no report
