Rebooting on PAIR state (Writing disable)
OpenVMS does not show the volumes of writing disable (e.g., SVOL_PAIR) at start-up of
system, therefore the SVOLs are hidden when rebooting in PAIR state or SUSPEND(read only)
mode. You are able to verify that the “show device” and “inqraid”command does not show
the SVOLs after reboot as below (notice that DGA148 and DGA150 devices are SVOL_PAIR).

After making the SVOL for Writing enable by using “pairsplit” or “horctakeover”
command, you need to perform the “mcr sysman” command in order to use the SVOLs
for back-up or disaster recovery.
$ pairsplit -g CAVG -rw
$ mcr sysman
