scvxinstall Creates Incorrect vfstab Entries When Boot Device is Multipathed (4639243)

Problem Summary: scvxinstall creates incorrect /etc/vfstab entries when boot device is multipathed.

Workaround: Run scvxinstall and choose to encapsulate. When the following message appears, type Ctrl-C to abort the reboot:

This node will be re-booted in 20 seconds. Type Ctrl-C to abort.

Edit the vfstab entry so /global/.devices uses the /dev/{r}dsk/cXtXdX name instead of the /dev/did/{r}dsk name. This revised entry enables VxVM to recognize it as the root disk. Rerun scvxinstall and choose to encapsulate. The vfstab file has the necessary updates. Allow the reboot to occur. The encapsulation proceeds as normal.
