NAME sam-stagerd - Invokes the SAM-QFS stage daemon SYNOPSIS /opt/SUNWsamfs/sbin/sam-stagerd AVAILABILITY SUNWsamfs DESCRIPTION The sam-stagerd process stages files in a SAM-QFS file system. Staging is the process of copying a nearline or offline file from its archive storage back to online storage. The SAM-QFS file system staging capability allows you to stage files immediately, to never stage files, and specify other staging actions. The sam-stagerd process is initiated by the sam-fsd daemon. By default, the stager uses the default behaviors described on the stager.cmd(4) man page. OUTPUT FORMAT The stager can produce a log file containing information about files staged. Here is an example: E 2004/02/02 15:23:43 lt ST0004 d2.1 11228.7 10485760 /sam9/testa 1 124 sam root 0 F 2004/02/03 14:37:41 lt CFX598 5410.23 15339.5 15703 /sam9/rdump 1 hm129959 other root 42 Field Description 1 C for stage cancel. E for error. F for stage finish. S for stage start. 2 Date of stage action. 3 Time of stage action. 4 Stage media. 5 VSN. For removable media cartridges, this is the volume serial name. For disk archives, this is the disk volume name and tar file path. 6 Physical position of start of archive file on media and file offset on the archive file / 512. 7 Inode number and generation number. The generation number is an additional number used in addition to the inode number for uniqueness since inode numbers get re-used. 8 Length of file if written on only 1 volume. Length of section if file is written on multiple volumes. 9 Name of file. 10 Copy number being staged. 11 User name of the file's owner. 12 Group of the file's owner. 13 User name of the requestor of the stage. 14 Equipment number from the mcf of the device on which the stage occurred. FILES If the stager command file is present in /etc/opt/SUNWsamfs/stager.cmd, the sam-stagerd process reads that file. SEE ALSO stage(1). sam-fsd(1M). stager.cmd(4).
