Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

3 CIP Configuration and Management
This chapter explains the tasks involved in configuring, running, and managing the CIP subsystem
on the NonStop host system and on the CLIM. Tasks that are only relevant for IP CIP, Storage CIP
or Telco CIP are identified throughout the text. For information about the LUN manager, see
Chapter 5 (page 170). The tasks covered in this chapter are:
CAUTION: Best Practice: You should always back up the configuration files after changing any
configuration information. For information on how to perform a backup, see“Managing the
Configuration Preservation” (page 113).
Using Linux Commands and Custom CIP Commands
Table 5: Sample Safe Linux Commands provides examples of Linux commands HP considers safe
to use with the CIP subsystem. For instructions on obtaining man pages and help for Linux
commands, see “Linux Man Page Documentation and Help” (page 25).
CAUTION: The CIP subsystem includes a front-end device running the Linux operating system. It
is safe to use Linux commands for simple operations, such as copying a file, searching a string,
or collecting logs. Table 5: Sample Safe Linux Commands shows examples of Linux commands
that are safe to use. Do not use any destructive Linux command on the CLIM. Using destructive
Linux commands can cause failure of the CIP subsystem.
NOTE: This table contains a number of network-sensitive commands that need to have a provider
specified when invoked on a CLIM with MULTIPROV ON. Those commands are flagged with an
X in the second column and are also listed under prov(1p).

Displays the Internet-to-Ethernet address translation tables used by the address
resolution protocol. See the arp man page for more information.
Xarp -a
Concatenates files and prints on the standard output. See the cat man page
for more information.
cat
Changes current directory. Use the help cd command for more information.cd
Prints or sets the system date and time. See the date man page for more
information.
date
Prints or controls the kernel ring buffer. See the dmesg man page for more
information.
dmesg
Displays ethernet card settings for the given interface. See the ethtool man
page for more information.
Xethtool
interface-name
Displays amount of free and used memory in the system. See the free man
page for more information.
free
Print lines matching a pattern. See the grep man page for more information.grep
HP ProLiant Integrated Management Logging (IML) utility. See the hplog
man page for more information.
Xhplog
Since hplog is not a network-sensitive command and its agents execute only
in %MAINT provider, hplog must always be executed in the ‘%MAINT’
provider.
Displays status of currently active interfaces. See ifconfig man page for
more information.
Xifconfig
