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Note: This tunable is obsolete.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 tun‐
able'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 parame‐
ter 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 val‐
ues. For information about the effects of installation on tunable val‐
ues, consult the documentation for the kernel software being installed.
