Technical data

MOUNT
Refer to the HP TCP/IP Services for OpenVMS Management manual for more
information.
/STRUCTURE
Optional. Default: /STRUCTURE=2
Specifies whether the volume should be formatted in Files-11 On-Disk Structure
Level 2 (ODS-2), which is the default, or Files-11 On-Disk Structure Level 5
(ODS-5).
For more information about ODS-5 disks, refer to the HP OpenVMS System
Manager’s Manual: Essentials.
/SUPERUSER=uid
/NOSUPERUSER
Optional. Default: /NOSUPERUSER.
Maps users with SYSPRV, BYPASS, or READALL privileges to the superuser
UID. The NFS server must allow superuser access.
The normal superuser UID is 0.
/NOSUPERUSER: No mapping.
/SYSTEM
Optional. Default: System mounted.
Places the logical name in the system logical name table unless you specify
the /GROUP or /SHARE qualifier. The client deletes the logical name from the
system table when you dismount the volume.
Restrictions:
• Requires SYSNAM privilege.
• The /GROUP, /SYSTEM, and /SHARE qualifiers are mutually exclusive.
• Without SYSNAM or GRPNAM privilege, you must use /SHARE for a job
mount.
/TIMEOUT=OpenVMS_delta_time
Optional. Default: ::01 (1 second).
Minimum timeout period for initial remote procedure call (RPC) request
retransmissions.
Specify the timeout period as your estimate of the typical round-trip time for RPC
requests. For slower-speed links — for example, NFS traffic over SLIP — specify
a value that is larger than the default.
Example: For a maximum read/write size of 8192 (see the /DATA qualifier) over
a 19,200-baud SLIP line, set the absolute minimum timeout value as follows:
10240 bytes*8 bits per byte
--------------------------- = 4.27 seconds
19,200 bits per second
Here, the 10240 bytes is 8192 data bytes plus the worst-case RPC overhead.
Because 4.27 seconds is the absolute minimum, a more realistic value for this
link is 15 to 30 seconds to allow for other traffic.
/UID=n
Optional. Default: –2.
