Using DRD Activate and Deactivate to Recover from Boot Problems

On an Integrity System
This EFI (Extensible Firmware Interface) address of the clone can be obtained on an Integrity system
by using the “-e” option on the ioscan command. The address can then be printed or stored on
another system. In the event that a boot from the clone is needed, the stored address can be
compared to those in the boot menus.
Figure 7 below shows the output of an ioscan command on an Integrity system. The administrator
needs to note which disk is the drd clone. In the display, the right-most field, “Description” has been
deleted to make
Figure 7 easier to read.
