NAME
scsimgr_eschgr - SCSI class driver eschgr plug-in for scsimgr
DESCRIPTION
The SCSI class driver eschgr plug-in for
scsimgr implements management and diagnostic operations
specific to classes of devices bound to the
eschgr driver. eschgr is the native HP-UX SCSI class driver
that handles, by default, all library/changer devices.
The plug-in handles the following operations for driver
eschgr:
• Display and clear driver
eschgr 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
eschgr on LUNs bound to it.
• Get, set and save driver
eschgr
global and per-lun instance attributes.
Commands
The user can explicitly send the following
scsimgr commands to driver eschgr plug-in by specifying the
-d eschgr 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 the syntax of the above commands.
However, the only instances where it is necessary to explicitly send a command to the plug-in is when per-
forming operations on objects global to driver eschgr: global statistics, attributes or status information.
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 eschgr or to their LUN paths.
Attributes
The following table lists driver eschgr 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.
• uint32 is unsigned 32 bits integer.
