Configuring the Dump-to-Disk Feature 

This section describes the steps necessary to initially configure the
dump-to-disk feature, using the BLDDUMP utility.  You should have already
defined your protection scheme and alternate dump device strategy.


NOTE  Before proceeding with this section, read each of the steps and
      become familiar with the BLDDUMP commands BUILD and TAPE. Both
      commands are described in detail later in this chapter.


The steps below describe how to create two new dump files, DUMP1 and
DUMP2, on a two-volume nonsystem volume set called DISKDUMP_VOLUME_SET.
The sample system supports 50 terminals during peak operating times.
Main memory size is 96 megabytes.

For more detailed information about BLDDUMP commands and features, refer
to "Managing the Dump-to-Disk[REV BEG] and Mini-Dump Features,"[REV END]
later in this chapter.

To configure the dump files, follow these steps:

   1.  Log on as MANAGER.SYS. At the system prompt, enter:

            :HELLO MANAGER [/userpass].SYS[/acctpass] 

   2.  Invoke the BLDDUMP utility.  At the system prompt, enter:

            :RUN BLDDUMP.HP36375.TELESUP 

   3.  Use the BUILD command to build a dump file, using the file size
       and protection scheme that you have already defined.  At the
       BLDDUMP prompt, enter:

            (#1) blddump > BUILD fileid file size protection 

       where: 

       fileid                The name of the dump file that you want to
                             create.  The fileid parameter can be up to
                             five alphanumeric characters in length and
                             must begin with an alpha character.  The
                             BLDDUMP utility appends the characters "MEM"
                             to the fileid.  For example, DUMP1 becomes
                             DUMP1MEM.

       file size             The size, in megabytes, of the dump file.

       protection            Indicates whether or not a dump file is
                             protected from overwrites.  If Y[es] is
                             specified, the dump file is protected from
                             overwrites by subsequent dumps to disk, if
                             it contains dump information.  If N[o] is
                             specified, subsequent dumps to disk can
                             write new dump data to the file, deleting
                             any existing data.  The YES option is the
                             default.

       If you want two or more dump files, use the BUILD command to
       create them.

   4.  Use the TAPE command to specify your alternate dump device
       strategy.  At the BLDDUMP prompt, enter:

            (#2) blddump > TAPE dump_strategy 

       where:

       dump_strategy         If Y[es] is specified, the dump facility
                             initiates dump-to-tape if dump-to-disk is
                             unsuccessful.  If N[o] is specified, the
                             dump facility terminates immediately if
                             dump-to-disk is unsuccessful.  If neither is
                             specified, TAPE defaults to YES.

   5.  Use the LIST command to display the current state of the
       dump-to-disk feature:  LIST displays information about the dump
       files that you just created and the dump strategy.

   6.  Use the EXIT command to exit BLDDUMP. At the BLDDUMP prompt,
       enter:

            (#3) blddump > EXIT 

   7.  When you exit BLDDUMP, invoke both VSCLOSE and VSOPEN against the
       nonsystem volume set.  This is necessary because you used the
       BUILD command, and it ensures posting of directory information.
       You must enter VSCLOSE and VSOPEN at the console.  At the system
       prompt, enter:

            :VSCLOSE DISKDUMP_VOLUME_SET 
            :VSOPEN DISKDUMP_VOLUME_SET
