bmgroup
114 Platform LSF Command Reference
bmgroup
displays information about host groups
Synopsis
bmgroup [-r] [-l] [-w] [host_group ...]
bmgroup [-h | -V]
Description
Displays host groups and host names for each group.
By default, displays information about all host groups including host groups created
for EGO-enabled SLA scheduling. A host partition is also considered a host group.
Host groups for EGO-enabled SLA
When hosts are allocated to an EGO-enabled SLA, they are dynamically added to a
host group created by the SLA. The name of the host group is
_sla_sla_name,
where sla_name is the name of the EGO-enabled SLA defined in
lsb.serviceclasses or in ENABLE_DEFAULT_EGO_SLA in lsb.params. One
of the hosts in the host group has the name
_virtual.
When the host is released to EGO, the entry is removed from the host group.
bmgroup displays the hosts allocated by EGO to the host group created by the SLA.
Options
-l Displays static and dynamic host group members. A ‘+’ sign before the host name
indicates that the host is dynamic and is currently a member of the host group. A ‘-’
sign before the host name indicates that the host is currently not an LSF host but is
a member of the dynamic host group.
Also identifies condensed host groups. These host groups are defined by
CONDENSE
in the
HostGroup section of lsb.hosts.
-r Expands host groups recursively. The expanded list contains only host names; it
does not contain the names of subgroups. Duplicate names are listed only once.
-w Wide format. Displays host and host group names without truncating fields.
host_group ... Only displays information about the specified host groups. Do not use quotes when
specifying multiple host groups.
-h Prints command usage to stderr and exits.
-V Prints LSF release version to stderr and exits.
Output
In the list of hosts, a name followed by a slash (/) indicates a subgroup.
Files
Host groups and host partitions are defined in the configuration file lsb.hosts(5).
