2 Operating System
The H06.08 RVU contains these operating system changes:
•
OSS ACLs
•
OSS Name Server Limits Relief
OSS ACLs
The H06.08 RVU adds support for access control lists (ACLs) for HP NonStop Open
System Services (OSS) regular files, directories, first-in/first-out (FIFO) special files,
and bound AF_UNIX sockets in OSS Version 3 filesets. OSS ACLs:
•
Provide finer access control than standard UNIX permissions
•
Support up to 150 ACL entries
•
Support separate permissions for up to 146 users and groups in addition to the
owner and the owning group
•
Support default ACL inheritance
•
Are based on the POSIX 1003.1e draft standard and the HP-UX implementation
Version 3 filesets are not supported on pre-H06.08 RVUs. To upgrade to a Version 3
fileset or to downgrade to a Version 2 fileset, you must use an H06.08 or later version
of the fsck utility.
As of the H06.08 RVU, Version 1 filesets are not supported. Version 2 filesets continue
to be supported. All new filesets created on systems running H06.08 and later H-series
RVUs are Version 3 filesets.
The OSS Network File System (NFS) does not support OSS ACLs.
For more information about OSS ACLs, see the acl(5) reference page either online
or in the Open System Services System Calls Reference Manual.
Migration
As of the H06.08 RVU, Version 1 filesets are not supported. You must upgrade Version
1 filesets to Version 2 or Version 3 filesets.
To use OSS ACLs, you must first migrate to the H06.08 RVU and then migrate your
existing filesets to Version 3 filesets. To migrate filesets, stop the OSS file system and
the OSS environment and use the fsck DIAGNOSE FILESET, UPGRADE command
as described in the Open System Services Management and Operations Guide.
To restore backup tapes from H06.08 and future RVUs onto H06.05 through H06.07
systems, you must install the T0744 Backup/Restore 2 SPR. No T0744
Backup/Restore 2 SPR is available for pre-H06.05 systems.
