5.5 HP StorageWorks X9720 Network Storage System Administrator Guide (AW549-96026, March 2011)

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.
The exds_stdiag utility does not access the utility file system, so it can be run even if storage
problems prevent the utility file system from mounting.
Syntax
# exds_stdiag [--raw=<filename>]
The --raw=<filename> option saves the raw data gathered by the tool into the specified file in a
format suitable for offline analysis, for example by HP support personnel.
Following is a typical example of output from this command:
