I/O Domains in Transition State After Reboot of Primary Domain (17020481)

In servers configured with logical domains and a large number of virtual functions, and where the failure-policy parameter is set to reset, if the primary domain is rebooted, the I/O and guest domains might hang in a transitional state.

Workaround: Before rebooting the primary domain, perform this procedure for each logical domain.

1. From the primary domain console, use the telnet command to access the OpenBoot on the logical domain.

2. At the OpenBoot prompt, set the boot-device parameter:

   ok> setenv boot-device disk disk disk disk disk disk disk disk disk disk net
   

   ---

   Note - The number of disk entries following setenv boot-device varies according to the number of virtual functions configured. The example provided is sufficient when more than 200 virtual functions are configured. When there are fewer virtual functions, fewer disk entries are required.

   ---

3. Verify the boot-device parameter with the printenv command.

4. Return to the primary domain console.

   ---

   Note - Do not boot the logical domain.

   ---

5. Repeat Step 1 through Step 4 for all logical domains on the system.

6. Reboot the primary domain.
