HP-UX System Administrator's Guide: Routine Management Tasks

NOTE: bsize in the resulting output is the configured block size, in bytes, of the file
system /work. But in JFS file systems, the configured block size determines only the
block size of the direct blocks , typically the first blocks written out to a new file.
Indirect blocks, typically those added to a file as it is updated over time, all have a
block size of 8 kilobytes.
See mkfs_vxfs(1M) for an explanation of each field in the output.
You can also run mkfs -m on an HFS file system, but the output is less friendly, lacking
the labels. dumpfs, with grep for the parameter you’re interested in, is better; see
“Checking NFS Server/Client Block Size” (page 194) for an example.
Managing Groups of Distributed Systems or Serviceguard Clusters
You can also use Distributed Systems Administration Utilities (DSAU) to monitor your
distributed cluster or network. DSAU can apply rules to each machine in the distributed
configuration. Using DSAU tools you can perform several tasks across groups of systems
or in a Serviceguard cluster. For additional information, refer to Distributed Systems
Administration Utilities (DSAU) User’s Guide.
Adding Peripherals
To add peripherals to your system, consult the following documentation:
• The hardware installation manual that came with the peripheral.
• For PCI OL* information, see the manual Interface Card OL* Support Guide. For PCI
OL* information on nPartition-able systems, see the manual nPartition
Administrator's Guide.
PCI OL*, previously known as OLAR, is the ability to add or remove a PCI card
without needing to completely shutdown the entire system. The system hardware
combined with operating system support allows per-slot power control. Instead
of turning off the entire system, you can turn off and on power to a specific PCI
slot.
PCI latches and doorbells refer to physical latches and buttons on the system itself
that allows for enabling and disabling power to a PCI slot.
The procedures for PCI OL* can be performed through a GUI, such as pdweb or
the Partition Manager, or through HP-UX commands, such as rad (olrad as of
11i v2). All are documented in the preceding manuals.
