• If the system that will be backed up has application processes active
at low run levels, establish a state of minimal activity (modified init 1
run level) and enter the single user mode to prevent errors after
recovery (see “Consistent and Relevant Backup” on page 444).
Consult your operating system documentation for details.
HP-UX Example
1. Move some kill links from
/sbin/rc1.d
to
/sbin/rc0.d
and
complement the changes for the boot-up section. The kill links
include the basic services that would otherwise be suspended by
moving to run level 1, and they are needed for the backup. For an
example, see Appendix A, “Disaster Recovery: Move Kill Links on
HP-UX 11.x,” on page A-25.
2. Ensure that
rpcd
is configured on the system (configure the
variable
RPCD=1
within the file
/etc/rc.config.d/dce
).
This prepares the system so that it enters the state of minimal
activity. The state can be characterized as follows:
—
Init-1
(
FS_mounted, hostname_set, date_set,
syncer_running
)
— Network must be running
— The following processes should also be running:
inetd
,
rpcd
,
swagentd
Solaris Example
1. Move the
rpc
kill link from
/etc/rc1.d
to
/etc/rc0.d
and
complement the change for the boot-up section. The kill links
include the basic services that would otherwise be suspended by
moving to run level 1, and they are needed for the backup.
2. Ensure that
rpcbind
is configured on the system.
This prepares the system so that it enters the state of minimal
activity. The state can be characterized as follows:
—
Init 1
— Network must be running
— The following processes should also be running:
inetd
,
rpcbind
.

— If the system is powered down, boot up the system and enter the
System Reference Manual (SRM) console (the firmware console).
Execute the following command from the SRM console to enter the
