DESCRIPTION¶
This is the IBM hypervisor virtual console server (hvcs)
administration utility.
OPTIONS¶
-all- Close all open vty-server adapter connections.
Inclusion of a single
‘-noisy’ flag will direct the
utility to output a list of all the adapters that were closed.
-close
hvcs<index>- Close the vty-server adapter connection that maps to the hvcs device node
specified in the option.
By default this operation only exhibits output on error. It is
silent on success and silent if the adapter is already closed. When
accompanied by a ‘-noisy’ flag
this option will output the device to adapter mapping and a message
indicating that the adapter has been closed.
-console
partition- Which /dev/hvcs<index> node provides the console for the option
specified partition? This option takes a partition number and returns a
status string which contains the device node that maps to the target
partition's slot zero vty-server adapter [A console adapter is always in
slot zero].
Inclusion of a single
‘-noisy’ flag does not change the
default output of this option.
-help- Output the utility help text.
-node
hvcs<index>- Which vty-server adapter is mapped to the option specified
/dev/hvcs<index> node? This option takes a device node and returns a
status string which contains the vty-server adapter mapped to that node.
Inclusion of a single
‘-noisy’ flag does not change the
default output of this option.
-noisy- This directive is optional. Without a
‘
-noisy’ directive the hvcsadmin
utility is in silent mode by default (except in the case of errors
and output requests). The output verbosity of the utility is managed by
stacking ‘-noisy’ directives. A
single instance of ‘-noisy’
indicates that the utility should output in status mode. A second
instance of ‘-noisy’ indicates that
the utility should output in verbose mode. Verbose mode is
generally used for script tracing and won't be used by a casual user
unless problems arise.
-rescan- Direct the hvcs driver to rescan partner information for all vty-server
adapters it manages. This may expose additional adapters and
partners.
-status- Outputs a table with each row containing a vty-server, adapter, its
/dev/hvcs<index> device node mapping, and the adapter connection
status. "vterm_state:0" means it is free/disconnected and
"vterm_state:0" means the vty-server is connected to its vty
partner adapter.
An example of hvcsadmin -status output follows:
vty-server@30000003 partition:1 slot:2 /dev/hvcs0 vterm-state:0
vty-server@30000004 partition:15 slot:0 /dev/hvcs1 vterm-state:0
When this option is accompanied by a
‘-noisy’ flag it will output a
line for each hvcs device node which doesn't have a current vty-server
adapter mapping as well as the status demonstrated above.
-version- Out the hvcsadmin script's version number.
