VALUES
Failsafe
Default
Allowed values
Recommended values
DESCRIPTION
Note: This tunable is obsolete. It is replaced by the attribute, which can be get and set using the command (see scsimgr(1M)).
This tunable sets the maximum data size the SCSI subsystem will accept for an I/O. Depending on the device's characteristics and the
device driver configuration, the maximum size allowed by the SCSI subsystem for a particular SCSI device might be lower than or equal to
this tunable's value. It will never be greater.
Who Is Expected to Change This Tunable?
Any customer.
Restrictions on Changing
Changes to this tunable will take effect when the device is first opened.
When Should the Value of This Tunable Be Raised?
The value should never be raised.
When Should the Value of This Tunable Be Lowered?
The value should never be lowered.
What Other Tunables Should Be Changed at the Same Time as This One?
None.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter has been obsoleted for HP-UX 11i Version 3.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
