HPACUCLI (HP Array Configuration Utility) is the primary tool for managing HP Array controllers on HP servers. It allows administrators to configure specific parameters of the server’s storage controller via both CLI and GUI interfaces. This utility is essential for maintaining high-performance storage in a production environment.
Key Points
- HPACUCLI helps configure RAID arrays and manage physical or logical drives on HP hardware. [cite: 2]
- The tool supports both command-line and graphical interfaces for flexibility in server management.
- Critical operations like enabling Write Cache or rescanning devices can be performed without rebooting.
- As MVPS provides unmanaged services, users are responsible for managing their own RAID configurations and software.
- Technical support ensures the underlying VPS and network are operational but does not cover OS-level tasks.
Before diving into the commands, it is useful to know the common abbreviations used in the utility: dwc (drivewritecache), ctrl (controller), ld (logicaldrive), pd (physicaldrive), and ch (chassisname).
How to install HPACUCLI on Linux?
On Linux machines, the tool can be installed by downloading the appropriate RPM package directly from the HP website. Proper installation is the first step toward managing your unmanaged storage environment effectively.
While managing your server hardware, you might also be running web applications. For those working on the software stack, understanding what is PHP and how it interacts with your database can be just as crucial as storage configuration.
Common HPACUCLI commands for controllers
To access the command prompt, simply type hpacucli. You can list all available controller commands by using hpacucli help. To show the full configuration and details of all controllers, use the following commands:
ctrl all show config ctrl all show config detail
If you need to check the current status of your controllers or modify the Write Cache settings, use:
ctrl all show status ctrl slot=0 modify dwc=enable ctrl slot=0 modify dwc=disable
How to manage physical and logical drives?
Managing physical drives is straightforward. You can show the status of all attached physical drives or target a specific drive using its slot and ID:
ctrl slot=0 pd all show status ctrl slot=0 pd 1:5 show detail
When working with logical drives, you can create various RAID levels depending on your needs. For example, to create a RAID 1 or RAID 5 array, use:
ctrl slot=0 create type=ld drives=2:4,2:5 size=500 raid=1 ctrl slot=0 create type=ld drives=1:3,1:4,1:5,1:6,1:7 raid=5
Remember that as these are unmanaged services, users have full control over their logical drive modifications, including expanding or deleting partitions.
ctrl slot=0 ld 2 add drives=1:4 ctrl slot=0 ld 1 delete
Using these commands helps maintain a reliable and high-performance server environment for your workloads. Enjoy!
