IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive ...

Note: Place the asnode option in the schedule definition only. Do not place itin the client options file, on the command line, or in any other location.For more information about the server scheduler commands, see IBM Tivoli StorageManager Administrator Command Reference.Start the schedules using the following client command:dsmc schedYou can also use the client acceptor daemon (dsmcad), with managedservices set toschedule in the systems options file.Notes:1. Each schedule can be started from a different machine or LPAR.2. After running the schedules, any proxied client will be able to query andrestore all of the backed up data.Scheduling for backing up a GPFS filesystemThe following examples show the administrative client server commands using thescheduler to back up a GPFS filesystem, using three nodes in the GPFS clusterwhich participate in the backup.1. The administrator defines four nodes on the Tivoli Storage Manager server:node_1, node_2, node_3 and node_gpfs. node_1, node_2 and node_3 are onlyused for authentication; all filespaces are stored with node_gpfs.REGISTER NODE node_1 mysecretpa5sREGISTER NODE node_2 mysecretpa5sREGISTER NODE node_3 mysecretpa5sREGISTER NODE node_gpfs mysecretpa5s2. The administrator defines a proxynode relationship between the nodes:GRANT PROXYNODE TARGET=node_gpfs AGENT=node_1, node_2, node_33. The administrator defines the node name and asnode name for each of themachines in their respective dsm.sys files:nodename node_1asnodename node_gpfs4. The administrator defines a schedule for only node_1 to do the work:DEFINE SCHEDULE STANDARD GPFS_SCHEDULE ACTION=MACROOBJECTS="gpfs_script"DEFINE ASSOCIATION STANDARD GPFS node_gpfs5. To execute the schedule on node node_gpfs, enter the client command:DSMC SCHEDAnother way to back up GPFS is to use Tivoli Storage Manager to look for theincremental changes. The GPFS filesystem can be divided into three branches andeach branch can be statically assigned to each node using the virtualmountpointoption. In the following example, you have a file system called /gpfs with threebranches: /gpfs/branch_1, /gpfs/branch_2, and /gpfs/branch_3.1. The administrator defines four nodes on the Tivoli Storage Manager server:node_1, node_2, node_3 and node_gpfs. node_1, node_2 and node_3 are onlyused for authentication; all filespaces are stored with node_gpfs.REGISTER NODE node_1 mysecretpa5sREGISTER NODE node_2 mysecretpa5sREGISTER NODE node_3 mysecretpa5sREGISTER NODE node_gpfs mysecretpa5s2. The administrator defines a proxynode relationship between the nodes:GRANT PROXYNODE TARGET=node_gpfs AGENT=node_1,node_2,node_3Chapter 4. Backing up your data 99
