Installing and Formatting Disks
76 VERITAS Volume Manager Administrator’s Guide
3. If you want to use enclosure-based naming, use vxdiskadm to add a non-persistent
simple disk to the bootdg disk group, change back to the enclosure-based naming
scheme, and then run the following command:
# /etc/vx/bin/vxdarestore
Note If not all the disks in bootdg go into the error state, you need only run
vxdarestore to restore the disks that are in the error state and the objects that they
contain.
Persistent Simple/Nopriv Disks in Non-Boot Disk Groups
If an imported disk group other than bootdg, consisting only of persistent simple and/or
nopriv disks, is put in the “online dgdisabled” state after the change to the
enclosure-based naming scheme, perform the following steps:
1. Deport the disk group using the following command:
# vxdg deport diskgroup
2. Use the vxdarestore command to restore the failed disks, and to recover the objects
on those disks:
# /etc/vx/bin/vxdarestore
3. Re-import the disk group using the following command:
# vxdg import diskgroup
Installing and Formatting Disks
Depending on the hardware capabilities of your disks and of your system, you may either
need to shut down and power off your system before installing the disks, or you may be
able to hot-insert the disks into the live system. Many operating systems can detect the
presence of the new disks on being rebooted. If the disks are inserted while the system is
live, you may need to enter an operating system-specific command to notify the system.
If the disks require low or intermediate-level formatting before use, use the operating
system-specific formatting command to do this.
Note SCSI disks are usually preformatted. Reformatting is needed only if the existing
formatting has become damaged.
The following sections provide detailed examples of how to use the vxdiskadm utility to
place disks under VxVM control in various ways and circumstances.
