HP Volume Shadowing for OpenVMS: OpenVMS Version 8.4 > Appendix A Messages

OPCOM Message

The following OPCOM message is returned in response to shadow set operations. This message results when the shadowing code detects that the boot device is no longer in the system disk shadow set. If the boot device is not added back into the system disk shadow set, the system may not reboot, and the dump may be lost if the system crashes.

virtual-unit: does not contain the member named to VMB. System may not reboot.

Explanation: This message can occur for the following reasons:

  • The boot device is dismounted or failed out of the system disk shadow set.

  • Shadowing finds the boot device missing from the system disk shadow set membership during any dismount operations on the system disk.

User Action: Do one of the following:

  • Mount the boot device back into the shadow set as soon as possible.

  • If you cannot mount the boot device back into the shadow set, change the device name in VMB (primary bootstrap) so the system can reboot when necessary.
