SC Alert: Host System has Reset

SC Alert: Host system has shut down.

Cause

The driver of vxio/vxdmp/vxspec is removed during p-patch upgrade procedure. The drivers will be added back during start procedure of the upgrade process. when startup procedure is skipped or installer is started using "-nostart" option then vxio/vxdmp/vxspec  driver will stay in removed state. During next reboot, system will fail to load the modules as their configuration was removed, this behavior is likely to cause system panic.

Resolution

This issue does not surface if patch VxFS 6.0.5.100 is installed using installFS605P1 without "-nostart" option or services are started during patch installation. Note that "-nostart" is an internal only option and should not be used with SFHA 6.x and higher. Future version of patches are going to address this in case where services were not started during patch installation. 
 
If  "installFS605P1 -nostart" was used to install the patch or services were not started during patch installation then use the following workaround to make sure the driver of vxio/vxdmp/vxspec have been added back to the system before issuing system reboot.
 
#add_drv vxdmp
#add_drv vxio
#add_drv vxspec
 

Applies To
