Chapter 3. Monitoring assets 165Figure 3-2 llstatus command flag descriptionThe llstatus command returns status information about machines in the LoadLevelercluster. For more information about the command reference details, see “Tivoli WorkloadScheduler LoadLeveler: Command and API Reference” in Table 3-1 on page 158.3.1.2 General Parallel File SystemIn 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 secondpart, we present specific IBM Power Systems 775 cluster examples that are introduced withthe GPFS Native RAID (GNR). For for information, see Table 3-1 on page 158.GPFS general commandsThe following general GPFS commands are used to manage the GPFS file system: mmdf mmgetstate mmlsdisk mmlsfs mmlsmount mmlsnsdThese commands are described in the GPFS information in Table 3-1 on page 158. Althoughthese commands belong to the GPFS base product, the output from the commands is not thesame. In this instance, the commands are mixed with specific IBM Power Systems 775 clusterGNR support. The following sections show the example outputs from these commands.mmdfExample 3-1 shows the mmdf command output.Example 3-1 mmdf command output# mmdf gpfs1disk disk size failure holds holds free KBfree KBname in KB group metadata data in full blocksin fragments--------------- ------------- -------- -------- ----- ---------------------------------------Disks in storage pool: system (Maximum disk size allowed is 10 TB)000DE22BOTDA1META 1048702976 -1 yes no 1048541184 (100%)1984 ( 0%)000DE22BOTDA2META 1048702976 -1 yes no 1048543232 (100%)3968 ( 0%)000DE22BOTDA3META 1048702976 -1 yes no 1048541184 (100%)1984 ( 0%)# llstatus -?llstatus [-?] [-H] [-v] [-W] [-R] [-F] [-M] [-l] [-a] [-C] [-b][-B {base_partition_list | all}] [-P {partition_list | all}][-X {cluster_list | all}] [-f category_list] [-r category_list][-L {cluster | machine_group | machine}][-h hostlist | hostlist]
