between the members by defining NetWorker as a highly available
application. By installing the NetWorker Server on each cluster member
and configuring cluster members as NetWorker servers, NetWorker will
automatically fail over as directed by the ASE manager. NetWorker subsets
are available on the Associated Products, Volume 2 CD-ROM in the
following subsets, where *** is the release number, such as 440:
• Release Notes and Documentation (BRXRNOTES***)
• Server for Tru64 UNIX (BRXSOAKIT***)
• Tru64 UNIX Client (BRXCKIT***)
• Reference Pages (BRXSMAN***)
All subsets are applicable to NetWorker SingleServer except for
BRXCKIT***. See the NetWorker Save and Restore for Tru64 UNIX
Software Product Description (SPD xx.xx) for a complete description of
features.
11.2 Creating a Standalone System Kernel on Tape
You can create a bootable Standalone System (SAS) kernel on tape. The
SAS kernel has a built-in memory file system (mfs), which contains the
minimum commands, files, and directories needed to restore the system
image. This is referred to as the miniroot file system.
To create the SAS kernel, you must use the btcreate utility. Once you
have created the kernel, you can restore the customized image using the
btextract utility. The following sections provide an overview of the
btcreate and btextract utilities. For information on syntax and
examples, see the reference page for each utility.
11.2.1 Restrictions on Building a Standalone System Kernel on Tape
The following restrictions apply to creating bootable standalone system
kernels on tape:
Although 32 MB memory configurations are no longer supported with this
release, you may want to create bootable tapes for such configurations
running previous versions of Tru64 UNIX (Digital UNIX). In this case, note
that bootable tape will not function with the -m mfs option for the
btcreate command on systems with 32 MB memory configurations. After
booting the kernel from tape, commands that use shared libraries will core
dump if you attempt to use this option. Use the -m ufs option while
creating the tape on systems with 32 MB memory configurations.
Bootable tape does not support the bootable kernel built with the
/usr/sys/conf/GENERIC kernel configuration file. Be sure to use a
system-specific custom kernel.
