DRD,系统映像克隆,用于操作系统的历史备份.当前OS出现故障,可以快速DRD恢复作业环境.
l 测试环境:HP-UX 11.23, IA ,RX6600
当前系统存在一个镜像,镜像盘为c2t1d0,c2t3d0,
用于DRD盘为c2t0d0.
l 未升级时DRD版本:1. 查看DRD版本信息及磁盘信息

DESCRIPTION
The drd command provides a command line interface to Dynamic Root Disk
(DRD) tools. The drd command has five major modes of operation:
clone
Clones a booted system to an inactive system image. The drd
clone mode copies the LVM volume group or VxVM disk group
containing the volume on which the root file system ("/") is
mounted.
mount
Mounts all file systems in an inactive system image. The
mount point of the root file system is either
/var/opt/drd/mnts/sysimage_000 or
/var/opt/drd/mnts/sysimage_001. If the inactive system
image was created by the most recent drd clone command, the
mount point of the root file system is
/var/opt/drd/mnts/sysimage_001. If the inactive system
image was the booted system when the most recent drd clone
command was run, the mount point of the root file system is
/var/opt/drd/mnts/sysimage_000.
umount
Unmounts all file systems in the inactive system image
previously mounted by a drd mount command.
runcmd
Runs a command on an inactive system image. Only a select
group of commands may be run by the runcmd mode. These are
commands which have been verified to have no affect on the
- 1 - Formatted: October 17, 2011
drd(1M) drd(1M)
booted system when executed by drd runcmd. Such commands
are referred to as DRD-Safe. The commands kctune,
swinstall, swjob, swlist, swmodify, swremove, swverify, and
view are currently certified DRD-Safe. An attempt to
execute any other command will result in a runcmd error. In
addition, not every software package may safely be processed
by sw* commands. The DRD-Safe SW-DIST commands are aware of
running in a DRD session and will reject any unsafe
packages. For more information about DRD-Safe packages, see
drd-runcmd(1M).
Standard input
activate
Sets the inactive system image to be the primary boot disk
the next time the system is booted.
deactivate
Sets the active system image (i.e. the booted image) to be
the primary boot disk the next time the system is booted.
Options
drd recognizes the following options:
-? Displays the usage message.
-x -?
Displays the list of possible -x (extended) options.
Return Values
drd major modes return the following values:
0 Success.
1 Error.
2 Warning.

To display all drd clone extended options:
drd clone -x -?
To mount the inactive system image:
drd mount
If the system image mounted was created by the most recent drd clone
command, the root file system will be mounted at
/var/opt/drd/mnts/sysimage_001.
If the system image was booted when the most recent drd clone command
was run, the root file system will be mounted at
/var/opt/drd/mnts/sysimage_000.
