Error description
The examples given to show how to schedule a backup of a GPFS file system need clarification in Tivoli Storage Manager manuals. Examples of how to schedule a backup of a GPFS file system The following example shows the steps necessary to back up a GPFS file system, using three nodes in the GPFS cluster to share the workload. This example assusmes node_1, node_2, and node_3 will be used for authentication. The file spaces backed up will be stored under node_gpfs. Define four nodes on the Tivoliᄅ Storage Manager server, using the following commands: (1) REGISTER NODE node_1 mysecretpa5s (2) REGISTER NODE node_2 mysecretpa5s (3) REGISTER NODE node_3 mysecretpa5s (4) REGISTER NODE node_gpfs mysecretpa5s Define a proxynode relationship between the nodes, using the following command: GRANT PROXYNODE TARGET=node_gpfs AGENT=node_1, node_2, node_3 Define a schedule for using the following commands: (1) DEFINE SCHEDULE STANDARD GPFS_SCHEDULE ACTION=incremental OBJECTS="/gpfs" (2) DEFINE ASSOCIATION STANDARD GPFS_SCHEDULE node_gpfs Choose one of the GPFS systems to run the schedule. Specify the following options in the dsm.sys file on the system chosen to run the schedule : (1) nodename node_1 (2) asnodename node_gpfs Start the scheduler on the system chosen to run the schedule: DSMC SCHED Tivoli Storage Manager Versions Affected: 5.5,6.1,6.2,6.3,6.4 Initial Impact: medium Additional Keywords: gpfs cluster sched backup proxy tsm

Problem conclusion
Section: Backing up your data > Backing up data with client-node proxy support (UNIX and Linux) > Scheduling backups with client-node proxy support > Examples of how to schedule a backup of a GPFS file system The example of scheduling a GPFS backup is updated as follows: Scheduling a backup of a GPFS file system Use the scheduler and proxy relationships to back up a GPFS file system. About this task Assume that three nodes in a GPFS cluster participate in the backup operation. Nodes node_1, node_2, and node_3 are used for authentication only. The objects are backed up to file spaces that belong to node node_gpfs. Procedure 1. Define four nodes on the Tivoli Storage Manager server. REGISTER NODE node_1 mysecretpa5s REGISTER NODE node_2 mysecretpa5s REGISTER NODE node_3 mysecretpa5s REGISTER NODE node_4 mysecretpa5s 2. Define a proxy relationship between the nodes. GRANT PROXYNODE TARGET=node_gpfs AGENT=node_1, node_2, node_3 3. Define a schedule. DEFINE SCHEDULE STANDARD GPFS_SCHEDULE ACTION=incremental OBJECTS="/gpfs" DEFINE ASSOCIATION STANDARD GPFS_SCHEDULE node_gpfs 4. Choose one of the GPFS systems to run the schedule. Specify the nodename and asnodename options in the dsm.sys options file on all systems in the GPFS cluster. The value for the asnodename option must be the same on all systems. Definitions in dsm.sys on node 1: nodename node_1 asnodename node_gpfs Definitions in dsm.sys on node 2: nodename node_2 asnodename node_gpfs Definitions in dsm.sys on node 3: nodename node_3 asnodename node_gpfs 5. Start the scheduler on the system that is chosen to run the schedule. DSMC SCHED
