When using wildcards, you must protect the HPSS file name from the shell with ' '. Each HPSS file will reside in a particular COS which, is selected when the file is first created. Once a COS is selected, it cannot be changed. COS is defined by the HPSS System Administrator. Automatic File Management HPSS files and their locations in the storage hierarchy are automatically managed.
Files move within the hierarchy through the migration, purging, and caching processes.
The disk cache, the top level of the hierarchy, is reserved for files which have most recently been accessed. Purging occurs when files on the disk cache exceed a preset limit of available space. A file residing on the top level, gives the user full access to it. Large Files HPSS imposes no limits on the size of a file, however, the length of a file name is limited to 256 characters. AIX limits the size of a file to 2 Gigabytes but has no restrictions on the length of a file name.
