NAME
scsimgr_estape - SCSI class driver estape plug-in for scsimgr
DESCRIPTION
The SCSI class driver
estape plug-in for scsimgr
implements management and diagnostic operations
specific to classes of devices bound to driver
estape. estape is the native HP-UX SCSI class driver
that handles, by default, all tape devices.
The plug-in handles the following operations for driver estape:
• Display and clear driver
estape global statistics and the statistics it maintains on instances of
LUNs bound to it, and on related LUN paths.
• Display status and other information maintained by driver
estape on LUNs bound to it.
• Get, set and save driver
estape
global and per-lun instance attributes.
Commands
The user can explicitly send the following scsimgr commands to driver
estape plug-in by specifying the
-d estape option:
clear_stat Clears statistics.
get_attr Displays information on attributes.
get_info Displays status and other information.
get_stat Displays statistics.
save_attr Saves value of attributes in a persistent store.
set_attr Set current values of attributes.
Note: Refer to scsimgr (1M) for syntax of the above commands.
However, the only instances where it is necessary to explicitly send a command to the plug-in is when
performing operations on objects global to driver
estape: global statistics, attributes or status informa-
tion. In all the other cases, scsimgr automatically invokes the plug-in to perform the driver specific
part of the operation, when the operation applies to LUNs bound to driver estape or to their LUN paths.
Attributes
The following table lists driver estape specific attributes. For details on the concept of attribute refer to
scsimgr (1M).
Note: The following conventions are used:
• RO is Read Only.
• RW is Read Write.
• VBM is Variable Block Mode.
• uint32 is unsigned 32 bits integer.
• uint64 is unsigned 64 bits integer.
• Range of values for applicable attributes is listed.
Object Attribute Name RO/RW Type Description
Version of driver estapeGlobal version RO string
norewind_
close_disabled
Disables the ability to open a "rewind"
device.
Default: 0
Values: 0 (disabled)
1 (enabled).
Note: This tunable was named
"st_san_safe" in releases prior to HP-UX
11i v3.
RW uint32
Determines whether to reserve the device
on open and release on close. See
st_ats_enable (5).
