Adding logical paths – HP StorageWorks XP Remote Web Console Software User Manual
Page 146
Figure 66 DKC Option Window
The DKC Option window displays the following settings:
•
The Minimum Paths option specifies the minimum number of paths required for each remote
storage system connected to the local storage system (default = 1).
NOTE:
You cannot change the Minimum Paths for the current version.
•
The RIO MIH Time setting specifies the RIO MIH timer value, which is the wait time until data
transfer from the local storage system to the remote storage system is complete. The RIO MIH
time value must be from 10 to 100 seconds. The default setting is 15 seconds.
NOTE:
When you will run the system with the 3DC cascading configuration, HP recommends
that the RIO (remote IO) MIH (missing interrupt handler) is set at 20 seconds.
Adding Logical Paths
The Add Path window (see
) allows you to add one or more logical paths
between the local and remote storage systems.
One primary storage system can be associated with up to 64 secondary storage systems. Up to
eight logical paths can be configured between one primary storage system and one secondary
storage system. When you add a logical path, Universal Replicator for Mainframe will automatically
start using the new logical path to perform Universal Replicator for Mainframe copy activities.
To add one or more new logical paths between the local and remote storage systems, follow the
procedure below. Not only the primary storage system administrator but also the secondary storage
system administrator can perform this operation.
1.
Make sure the remote copy connections are properly configured.
2.
Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP XP24000/XP20000 Remote Web
Console User's Guide.
3.
Ensure that the DKC Operation window is displayed.
4.
In Display, select DKC.
5.
Do either of the following:
•
In the tree, select a remote storage system.
•
In the list, select and right-click a remote storage system and then select Edit Path(s) from
the pop-up menu. The list displays information about logical paths.
6.
Right-click the list and then select Add Path from the pop-up menu.
The Add Path window appears (
