Figure 3-2 llstatus command flag description
The llstatus command returns status information about machines in the LoadLeveler
cluster. For more information about the command reference details, see "Tivoli Workload
Scheduler LoadLeveler: Command and API Reference" in Table 3-1 on page 158.
3.1.2 General Parallel File System
In this section, we present two distinct General Parallel File System (GPFS) monitoring areas.
For the first part, examples illustrate the general GPFS monitoring point of view. In the second
part, we present specific IBM Power Systems 775 cluster examples that are introduced with
the GPFS Native RAID (GNR). For for information, see Table 3-1 on page 158.
GPFS general commands
The following general GPFS commands are used to manage the GPFS file system:
mmdf
mmgetstate
mmlsdisk
mmlsfs
mmlsmount
mmlsnsd
These commands are described in the GPFS information in Table 3-1 on page 158. Although
these commands belong to the GPFS base product, the output from the commands is not the
same. In this instance, the commands are mixed with specific IBM Power Systems 775 cluster
GNR support. The following sections show the example outputs from these commands.
mmdf
Example 3-1 shows the mmdf command output.
