Figure 26 Split Volume Pair window
The Split Volume Pair window lists the volume(s)/pair(s) selected on the ShadowImage main window, and
shows the pair status and copy pace for each pair. Use the Copy Pace box to select the copy pace for all
pairs that you are splitting: Slower, Medium, or Faster. Use the Select Split Type box to select the split type
for all pairs that you are splitting: Quick Split or Steady Split. CLPR indicates the cache logical partition of
the T-VOL.
Use the Select T-Vol box to filter the T-VOLs displayed in the T-VOL list. Use the Internal Vol box to select
available T-VOLs that are internal volumes. Use the External Vol box to select the available T-VOLs that are
external volumes. The CU and Reserve boxes display the available S-VOLs by port and by reserve attribute.
The Set button adds the selected T-VOL to the selected S-VOL. The Change button replaces the T-VOL of the
selected pair in the list with the selected T-VOL. To remove any volumes from the list, select the unneeded
volumes, right-click to display the pop-up menu, and then click Delete. The OK button reflects all settings to
the Preset Volume List box on the ShadowImage main window.
NOTE: Click Apply on the ShadowImage main window to split all pairs in the Preset Volume List box. The
Cancel button closes the Pairsplit window without changing the settings.
To split one or more existing SI390 pairs:
1. If you want the split T-VOLs to be identical to the S-VOLs, stop all write operations to the S-VOLs before
splitting the pairs. This ensures that there are no updates to the S-VOLs while the split operations are
synchronizing the T-VOLs to the S-VOLs.
