The first host is the default master. If the first host is down, the second host takes over as master, and so on. If you install the LSF Batch working directory in a local filesystem on one host, only that host can act as the LSF master. You must list this host first in the lsf.cluster. cluster file. If this host goes down, LSF Batch becomes unavailable.
Batch processing resumes when the master host becomes available again.
Interactive load sharing is still available while the host is down. With this setup, the master daemon can be run on the hosts that have this directory mounted. If some of your directories are defined in AFS, you must klog as the primary LSF administrator before running lsfsetup . Get the additional LSF AFS tar distribution file from tape or downloaded from Platform Computing's WWW or FTP sites. Uncompress the compressed tar distribution file.
