3. Check the file systems and logical volumes that are created by the  lsvg  and l sfs commands, as shown in Example 7-84. 4. Because both active and standby instances are on the same hdisk0, you can set the boot  list to first check the standby instance, and then check the active instance. 5. Restart and see how the instance activates. Determine and confirm which instance was  used to start, as shown in Example 7-86.

Setting the boot list to put the standby instance first and then the current active instance  requires specifying the BLV name, as shown in Example 7-85.
