Replication
206 VTL User Guide • May 2008 G • 96267
‐w (‐‐watermark) is a data size based trigger in MB. The watermark is checked when
the tape is unloaded from the tape drive and the replication is triggered if the
amount of new data on the tape has reached the specified watermark.
‐d (‐‐date) combined with ‐i (‐‐interval) is a time based trigger. The replication is
triggered at the time specified by date and then repeated every interval. ‐d (‐‐date)
format is YYYYMMDDHHMM and ‐i (‐‐interval) format is a number followed by H
for hours or M for minutes (e.g. ‐i 2H or ‐‐interval=120M).
To delete a watermark trigger specify 0 for the watermark. To delete a time based
trigger specify NA for date. At least one trigger must remain active.
The date argument is not required if you are only changing the interval.
For virtual tapes having the tape caching property enabled, replication is triggered
based on the tape caching policy:
‐r (‐‐repl‐first) is required to replicate the virtual tape before it is migrated. Use ʺonʺ
in order to enable this policy or ʺoffʺ to have tape migration executed first.
The replication retry policy can be changed using the following options:
■ ‐t (‐‐replication‐timeout) in seconds (default 60).
■
‐I (‐‐replication‐retry‐interval) in seconds (default 60).
■ ‐C (‐‐replication‐retry‐count) retry count (default 1).
‐c (‐‐compression) is an option to enable or disable compression with one of the
values: on or off.
‐e (‐‐encryption) is an option for remote replication only to set the encryption with
one of the values: on or off.
‐X (‐‐rpc‐timeout) is an option to specify a number between 1 and 30000 in seconds
for the RPC timeout. The system will retry the command for the amount of time
specified if the server does not respond. The default RPC timeout is 30 seconds.
Get replication properties
iscon getreplicationproperties -s [-u -p ]
-v [-X ]
iscon getreplicationproperties --server-name=
[--server-username= --server-password=]
--source-vdevid= [--rpc-timeout=]
Description:
This command allows you to get the replication properties for a virtual device
configured for replication.
