NORMALIOMODE { UNBUFFEREDCP | DP2BUFFEREDCP | OSSBUFFEREDCP | DP2BUFFERED
| OSSBUFFERED }
specifies the input/output buffering and fault tolerance for application file opens that do not
use the O_SYNC option:
DescriptionValue
Use unbuffered input/output with checkpointing. This behavior provides maximum fault
tolerance but with reduced performance.
UNBUFFEREDCP
Use disk-process-buffered input/output with checkpointing. This behavior provides fault
tolerance for single failures, with better performance than UNBUFFEREDCP. DP2 buffers
DP2BUFFEREDCP
file data and checkpoints the file state to its backup process to ensure recovery from
single failures.
Use OSS-buffered input/output with checkpointing. This behavior provides fault tolerance
for single failures, with better performance than DP2BUFFEREDCP. OSS filesystem
OSSBUFFEREDCP
processes and DP2 share responsibility for buffering file data; OSS provides the buffering
whenever possible. DP2 checkpoints the file state to its backup process to ensure recovery
from single failures.
Use disk-process-buffered input/output without checkpointing. This behavior provides no
fault tolerance, but better performance than DPBUFFEREDCP.
DP2BUFFERED
Use OSS-buffered input/output without checkpointing. This behavior provides no fault
tolerance, but better performance than OSSBUFFEREDCP.
OSSBUFFERED
If NORMALIOMODE is not specified, the default behavior is OSSBUFFEREDCP.
REPORT filename3
specifies the Guardian filename for the report file to be generated when FSCK performs an
automatic recovery for this fileset. The file specified must be a Guardian spooler location.
If this option is omitted, FSCK uses the Guardian filename specified for the SUBSYS REPORT
option.
RESTRICTEDACCESS { DISABLED | ENABLED | LOCAL }
(J06.11 and later J-series RVUs or H06.22 and later H-series RVUs only) Specifies whether the
super ID is denied special privileges for accessing files in these filesets:
DescriptionValue
This is an unrestricted fileset. Security for this fileset is the same as security for OSS filesets
on systems running J06.10 and earlier J-series RVUs and H06.21 and earlier H-series
DISABLED
RVUs. This is the default value. To use the ADD FILESET command to add a fileset with
a RESTRICTEDACCESS attribute of DISABLED, you must be a member of the super-group
(255,nnn).
Specifies that this is a restricted-access fileset and that only NonStop systems that support
restricted-access filesets can remotely access this fileset. To use the ADD FILESET command
ENABLED
to add a fileset with a RESTRICTEDACCESS attribute of ENABLED, you must be logged
on to the local system as a user ID that is a member of the Safeguard
SECURITY-PRV-ADMINISTRATOR (SPA) security group and a member of the super group
(255, nnn), but is not the super ID (255, 255) or a member of the Safeguard
SECURITY-OSS-ADMINISTRATOR (SOA) group. See also “Considerations” (page 262).
Specifies that this is a restricted-access fileset and that NonStop systems can remotely
access this fileset whether or not the systems support restricted-access filesets. To use the
LOCAL
ADD FILESET command to add a fileset with a RESTRICTEDACCESS attribute of LOCAL,
you must be logged on to the local system as a user ID that is a member of the Safeguard
SECURITY-PRV-ADMINISTRATOR (SPA) security group and a member of the super group
(255, nnn), but is not the super ID (255, 255) or a member of the Safeguard
SECURITY-OSS-ADMINISTRATOR (SOA) group. See also “Considerations” (page 262).
