5. Locate the Wrt pol field in the Logical Drive list.
The write policy is shown as either write-through (WT), which
is the default setting, or write-back (WB).
6. Select the logical drive whose write policy you want to change.
Attention : If you change the write policy to WB, wait at least
10 seconds after your last operation before you turn off your
system. It takes that long for the system to move the data from
the cache memory to the storage device. Failure to follow this
practice can result in lost data.
7. Press Enter to change the write policy.
Notice that WT changes to WB. You can press Enter to toggle
between WT and WB.
8. Press Esc. The Confirm pop-up window appears asking you to
confirm your action.
9. Select Yes to save the changes. Select No to return the setting to
its original state.
10. Back up the disk-array configuration information to diskette.
