disk groups. Select Parity Group to overwrite control blocks in the volumes in parity groups.
The list shows disk groups or parity groups.
7. Check the list by taking the following steps:
a. Check the list to see whether Write To Control Blocks is displayed to the right (that is, in
the Action column) of the disk groups or parity groups whose control blocks should be
overwritten.
If Write To Control Blocks is not displayed, select the disk groups or the parity groups,
and then click Set. The Action column will display Write To Control Blocks.
b. Check the list to see if nothing is displayed to the right (that is, in the Action column) of
the disk groups or parity groups whose control blocks should not be overwritten.
If anything is displayed, select the disk groups or the parity groups, and then click Release.
The Action column will become empty.
When the Format All dialog box is displayed, all entries in the Action column are Write
To Control Blocks, which means that control blocks in all the disk groups or all the parity
groups will be overwritten.
If you change the selection in Target when any of the entries in the Action column are
empty, all the entries in the Action column will change to Write To Control Blocks.
8. Click OK to close the Format All dialog box. A message appears and asks if you want to
apply the settings.
