Configurationinformation can include registeredadministrator IDs, policies, clientschedules, client option sets,administrative schedules, storage managercommand scripts, server definitions, andserver group definitions. See alsoconfiguration manager and managed server.(1) For HSM on AIX, UNIX, or Linuxsystems, the limit (in megabytes) on theamount of data that can be migrated andpremigrated from a file system to serverstorage.(2) For HSM on Windows systems, auser-defined limit to the space that isoccupied by recalled files.RrandomizationThe process of distributing schedule starttimes for different clients within aspecified percentage of the schedule'sstartup window.raw logical volumeA portion of a physical volume that iscomprised of unallocated blocks and hasno journaled file system (JFS) definition.A logical volume is read/write accessibleonly through low-level I/O functions.read-without-recall recall modeA mode that causes hierarchical storagemanagement (HSM) to read a migratedfile from storage without storing it backon the local file system. The last piece ofinformation read from the file is stored ina buffer in memory on the local filesystem. Contrast with normal recall modeand migrate-on-close recall mode.rebindTo associate a backed-up file with a newmanagement class name. For example,rebinding occurs when the managementclass associated with a file is deleted. Seealso bind.recall In Tivoli Storage Manager, to copy amigrated file from server storage back toits originating file system using the spacemanagement client. See also transparentrecall, selective recall, and recall mode.recall modeA mode that is assigned to a migrated filewith the dsmattr command thatdetermines how the file is processedwhen it is recalled. It determines whetherthe file is stored on the local file system,is migrated back to Tivoli StorageManager storage when it is closed, or isread from Tivoli Storage Manager storagewithout storing it on the local file system.receiverA server repository that contains a log ofserver and client messages as events. Forexample, a receiver can be a file exit, auser exit, or the Tivoli Storage Managerserver console and activity log.
