◆ FLOAT_CLIENTS_ADDR_RANGE=100.172.1.13 100.*.30-54 124.24-
*.1.*-34
All client hosts belonging to a domain with the address 100.172.1.13 will be allowed
access. All client hosts belonging to domains starting with 100, then any number,
then a range of 30 to 54 will be allowed access. All client hosts belonging to domains
starting with 124, then from 24 onward, then 1, then from 0 to 34 will be allowed
access.
◆ FLOAT_CLIENTS_ADDR_RANGE=12.23.45.*
All client hosts belonging to domains starting with 12.23.45 are allowed.
◆ FLOAT_CLIENTS_ADDR_RANGE=100.*43
The * character can only be used alone, to represent the full range of possible
values; it cannot be used to represent a single digit in a number. In this example, an
error will be inserted in the LIM log and no hosts will be accepted to become LSF
floating clients.
◆ FLOAT_CLIENTS_ADDR_RANGE=100.*43 100.172.1.13
Although one correct address range is specified, because *43 is not correct format,
the entire line is considered incorrect. An error will be inserted in the LIM log and
no hosts will be accepted to become LSF floating clients.
Checking that security is enabled
Take this step after you have configured security. You are shown how to check that
security has been configured properly.
After you configure FLOAT_CLIENTS_ADDR_RANGE, check the master LIM log
file on the LSF master host (LSF_LOGDIR/
lim.log.master_host_name) to
make sure this parameter is correctly set. If this parameter is not set or is wrong, this will
be indicated in the log file.
Verifying LSF floating client license is working
Perform this procedure after setting up your floating client license to verify that your
floating client license is enabled.
To verify floating LSF Floating Client is enabled:
1 Start a cluster.
2 Submit the lshosts command from a host listed in
lsf.cluster.cluster_name:
% lshosts
In the following example, only hostA and hostB are defined in
lsf.cluster.cluster_name. HostA is a server and master host, and hostB is a
static client. If you type the command from
hostA or hostB, you will get the
following output:
% lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
hostA SUNSOL DEFAULT 1.0 1 128M 602M Yes ()
hostB SUNSOL DEFAULT 1.0 - - - No ()
