Remote Copy and 3PAR Virtual Domains

Remote Copy User’s Guide InForm OS Version 2.3.1

2.9.6 Throughput Limiting Option

For asynchronous periodic mode Remote Copy (see Asynchronous Periodic Mode on

page 2.24), it might be useful to use the throughput limiting option when setting up links over

leased lines. This option limits the maximum throughput that Remote Copy will utilize for a

link. This is useful, for example, if the leased line charges are based on the bit rate utilized. If

this option is not used, Remote Copy attempts to send data as fast as it can on both links. If the

limit is set, the data is metered and sent out at a rate less than or equal to the set limit. For

instructions on setting this limit, see Limiting Throughput on page 4.10.

2.9.7 Role Reversal

While using Remote Copy, it is possible to reverse the roles of the volume groups. By reversing

roles, the primary becomes the backup and vice versa. To correct the reversal, you must change

the roles once again. See Reversing Target Designations on page 4.2 for specific instructions on

role reversal. Error Handling on page 2.35 also discusses role reversal.

2.10 Remote Copy and 3PAR Virtual Domains

Remote Copy checks for 3PAR Virtual Domains (domains) on the remote system to ensure the

virtual volume is mirrored to the same domain name as the local domain name. The domain

needs to be called a correct domain name. See the 3PAR InForm OS Concepts Guide for

detailed information about domains, and see the 3PAR InForm OS CLI Administrator’s Manual

for instructions on setting up domains.

NOTE: 3PAR Virtual Domains requires a 3PAR Virtual Domains license. For

additional information about the license, see the 3PAR InForm OS Concepts

Manual.
