Removing the error state for simple or nopriv disks in the boot disk group
If the boot disk group (usually aliased as bootdg) is comprised of only simple and/or nopriv disks, the vxconfigd daemon goes into the disabled state after the naming scheme change.
To remove the error state for simple or nopriv disks in the boot disk group
- Use vxdiskadm to change back to operating system-based (c#t#d#s#) naming.
- Enter the following command to restart the Volume Manager (VxVM) configuration daemon:
# vxconfigd -kr reset
- If you want to use enclosure-based naming, use vxdiskadm to add a sliced disk to the bootdg disk group, change back to the enclosure-based naming scheme, and then run the following command:
# vxdarestore
