You can also access the OA serial port using the supplied dongle from a blade. This can be useful
if you accidently misconfigure the VC networking so that you cannot access the OA through the
network. You access the serial port as follows:
1. Connect the dongle to the front of one blade.
2. Connect a serial cable from the OA serial port to the serial connector on the dongle.
3. Log in to the server via the TFT keyboard/mouse/monitor.
4. Run
minicom
as follows:
# Mincom
5. Press Ctrl-A , then p . The Comm Parameters menu is displayed.
6. Select 9600 baud .
7. Press Enter to save.
8. Press Ctrl-A , then m to reinitialize the modem. You are now connected to the serial interface
of the OA.
9. Press Enter .
10. When you are finished, press Ctrl-A , then q to exit minicom.
Accessing the Onboard Administrator (OA) via service port
Each OA has a service port (this is the right-most Ethernet port on the OA). This allows you to use
a laptop to access the OA command line interface. See HP BladeSystem c7000 Enclosure Setup
and Installation Guide for instructions on how to connect a laptop to the service port.
Using hpacucli – Array Configuration Utility (ACU)
The
hpacucli
command is a command line interface to the X9700c controllers. It can also be
used to configure the E200i and P700m controllers (although HP does not recommend this).
Capacity blocks come pre-configured. However, the
hpacucli
utility is useful if you need to
configure LUNs. It also allows you to look at the state of arrays. (Also, see the
exds_stdiag
utility).
Use the
hpacucli
command on any server in the system. Do not start multiple copies of
hpacucli
(on several different servers) at the same time.
CAUTION: Do not create LUNs unless instructed to do so by HP Support.
The exds_stdiag utility
The
exds_stdiag
utility probes the SAS storage infrastructure attached to an X9720 Network
Storage System. The utility runs on a single server. Since all the SAS fabric is connected together
it means that
exds_stdiag
can access all pieces of storage data from the server where it runs.
Having probed the SAS fabric the
exds_stdiag
utility performs a number of checks including:
•
Checks there is more than one path to every disk and LUN.
•
Checks that devices are in same order through each path. This detects cabling issues (for
example, reversed cables).
•
Checks for missing or bad disks.
•
Checks for broken logical disks (RAID sets).
•
Checks firmware revisions.
•
Reports failed batteries.
The
exds_stdiag
utility prints a report showing a summary of the storage layout, called the map.
It then analyzes the map and prints information about each check as it is performed. Any line
starting with the asterisk (*) character indicates a problem.
