Chapter 6 Recycling 163

▼ To Remove -recycle_ignore and ignore

Parameters

If you have used the -recycle_ignore or ignore parameter to disable recycling

during configuration, use this procedure to remove them. As an alternative to the

following procedure, you can use the File System Manager. For more information,

see the File System Manager online help.

1. Use vi(1) or another editor to remove the -recycle_ignore parameters from the

archiver.cmd file.

2. Use vi(1) or another editor to remove the ignore parameters from the

recycler.cmd files.

You are now recycling.

Recycling for Archive Copy Retention

As an alternate to the normal recycling process, the sam-nrecycler(1M) tool can

be used to work in conjunction with the File System Manager’s backup and recovery

point features. This tool removes expired archive copies and frees up archive

volumes to aid in the ability to use Sun StorageTek SAM dump files for archive

retention. If you want to take advantage of this functionality, you must use this

recycler in place of the existing sam-recycler command.

The sam-nrecycler(1M) tool scans file system metadata and Sun StorageTek SAM

dump files to determine which removable media and disk archive volumes contain

archive images. It can be invoked through the crontab(1) file at an off-peak time, or

invoked at any time using the sam-nrecycler command. The nrecycler identifies

all archive images present on a removable media volume or in a disk archive tar file

by scanning all file system .inodes files and specified Sun StorageTek SAM dump

files. By scanning the file systems and Sun StorageTek SAM dump files, the

nrecycler can determine if there are volumes that do not contain any archive

images, and the space on these volumes can be reclaimed. If a removable media

volume does not contain any archive images, it is safe to relabel the cartridge. If a

disk archive tar file does not contain any archive images, it is safe to remove the tar

file from the disk archive directory.

Directives for sam-nrecycler(1M) must be provided using the

/etc/opt/SUNWsamfs/nrecycler.cmd file. You must specify a path to the

directories that contain the Sun StorageTek SAM dump files to be searched. If no

directories are specified in the command file, recycling does not occur. The list of

directories must be complete and all Sun StorageTek SAM dump files must be

contained in the directory list.
