OSS ACLs
the new SPR supports DST transition for 2007 and later for the TABLE option. If you
fall back, a system load is required.
OSS ACLs
The G06.29 RVU adds support for access control lists (ACLs) for 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-G06.29 RVUs. To upgrade to a Version 3
fileset or to downgrade to a Version 2 fileset, you must use a G06.29 or later version of
the fsck utility.
As of the G06.29 RVU, Version 1 filesets are not supported. Version 2 filesets continue
to be supported. All new filesets created on systems running G06.29 and later G-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.
To restore backup tapes containing files on systems running G06.29 and later G-series
RVUs onto systems running the G06.23 through G06.28 RVUs, install these Backup
and Restore 2 and file system SPRs:
•
Backup and Restore 2 SPRs:
°
T2721G06^AAL, BRCOM
°
T2722G06^AAL, BR2 TAPE SERVICES
°
T2749G06^AAL, BR2 DMA & CSP
°
T2750G06^AAL, B/R 2 DATA SERVICE
•
The file system SPR T9055G11^AFI (for G06.23 through G06.26 RVUs) or
T9055G12^AFJ (for G06.27)
These SPRs are required because changes have been made to the information stored
with each object.
Note. For G06.28, the required file system SPR is already included in the G06.28 SUT.
