VCS firmware upgrades
When upgrading VCS firmware, both contro llers becom e inoperative. Under normal operating
conditions, Secure Path for AIX fails when both controllers are inoperative. However, this release

1. Change to the /usr/hp_hsv110 or /usr/hp_hsv100 directory.
2. Enter the /pause_io command.
3. Enter y when prompted.
4. Update the VCS firmware as directed in the VCS documentation.
This will take about 10 minutes.
5. after the EVA controllers are back o nline as indicated on the Command View EVA display, press
Enter to restart the I/O.
