NAME
lssf - list a special file
SYNOPSIS
special_file ...
special_file
DESCRIPTION
In the first form, lists information about a special file. For each special_file name, determines the major number of the special file and
whether it is block or character (using It then scans the system for the device that is associated with the special file. When the device
is found, the minor number of the special file is decoded.
A mnemonic description of the minor number is printed on standard output along with the hardware path (in other words, address) of the
device. Mnemonics used to describe the fields are closely related to the options used with (see mksf(1M)).
In the second form, displays the list of stale device special files present in selected directories under the directory.
In the third form, executes a Critical Resource Analysis (CRA) on the

Displays the stale device special files present in the
directories below, which contain special files for mass storage devices. The stale device special files correspond to nodes
that have an entry in the system I/O configuration files but the corresponding device is not found. The device special files
can either be legacy or persistent (see intro(7)).
DIAGNOSTICS
Most diagnostic messages from are self explanatory. Listed below are some messages deserving further clarification. Warnings allow to
continue.
Warnings
There is no information about the device in the kernel.
The special file is not usable. Use to remove the special file (see rmsf(1M)).
The major number associated with the special file is not in the kernel.
Use to add the appropriate driver to the kernel (see kcmodule(1M)).
The indicated device driver or device class
is not present in the kernel. An of a special file pointing to an unusable device fails. To make the device usable, the appro-
priate device driver and/or device class must be added to the kernel using If the device is no longer needed, should be used to
remove the special files and update the system I/O configuration files.
The file is not associated with an IO device.

NAME
ioinit - test and maintain consistency between the kernel I/O data structures and the ioconfig files
SYNOPSIS
DESCRIPTION
Starting with HP-UX 11i Version 3, there are two ioconfig files, which is the same as on prior releases and which contains additional agile
entries (see intro(7) for information on agile addressing). These two ioconfig files will have their copies in as and respectively.
The command is invoked by the process when the system is booted, based on the entry in
where
is a script to invoke with the and options. Given the option, checks consistency between the versions of ioconfig files and the
versions of ioconfig files. If these files are consistent, invokes to install special files for any new devices found.
If versions of ioconfig files are inconsistent with versions, updates versions of ioconfig files from versions and, if the option is given,
reboots the system.
If or is corrupted or missing when the system reboots, brings the system up in single-user mode. The user should then restore or accord-
ingly from backup or invoke with the option to recreate and from the kernel.
If the option is given, reassigns instance numbers to existing devices within a given class based on infile. If the driver associated with
the given hardware path does not support online instance number reassignment, reboot is required. If finds no errors associated with the
reassignment, and the option is given, the system is rebooted. (See the section.)
If the option is used with option, the command performs Critical Resource Analysis (CRA) on all the devices corresponding to the hardware
paths specified in infile, before assigning the new instance numbers. Existing device special files of LUNs, whose instance number is to
be reassigned, will be deleted and recreated after the reassignment of instance numbers. If the driver associated with the given hardware
path does not support online instance number reassignment, the option must be used.
If the option is given, recreates and from the existing kernel I/O data structures.
If the option is given, verifies if there is any corruption in the specified system file.
If the option is given, the kernel is forced to reassign instance numbers, starting from 0, for existing devices with the given class_name
on the next reboot. Note that this option must be used with the option, which reboots the system immediately, if the operation is success-
ful.
Options
recognizes the following options:
Performs Critical Resource Analysis (CRA) on all the devices
corresponding to the hardware paths specified in infile. Instance numbers will be reassigned as specified in infile, only
if CRA of all these devices report SUCCESS. Existing device special files of LUNs whose instance number are reassigned
will be deleted and recreated with the updated instance numbers.
The option must be specified when using the option. (See the option below.)
If the driver associated with at least one given hardware paths does not support online instance number reassignment, the
option must also be specified. (See the option below.) If the infile contains a hardware path of a node whose driver
does not support online instance number reassignment and option is not specified, the command aborts the operation.
Recreates and files from the kernel if any of these files are missing or cannot be restored from backup. Whenever updates these
files from information obtained from the kernel, it saves the current ioconfig file (the last known good one) before
updating them as and in order to keep them synchronized with kernel I/O data structures. If ioconfig files are missing or
corrupt, users are advised to copy the file from the last known good file so that the least amount of information is lost.
If is invoked, any previous binding of hardware path to device class and instance number may be lost.
Forces the kernel to reassign instance numbers starting from
0 for all existing devices with the given class_name. This option must be used with the option. On successful completion
the system is rebooted immediately.
Use the file
infile to reassign instance numbers to devices within a specified class. infile may have multiple entries, each to appear
on a separate line, each field in the entry separated by one or more blanks. Entries should conform to the following for-
mat:
h/w_path class_name instance_#
preprocesses the contents of infile, looking for invalid entries, and prints out explanatory messages. An entry is con-
sidered to be invalid if the specified hardware path or class name does not already exist in the system. If the specified
instance number already exists for the given class, the entry is invalid if it is not for circular reassignment. On suc-
cessful completion of this operation, previous special files will still be associated with the device.
Invoke to install special files for new devices after checking consistency between the versions of the ioconfig files and the
versions. This creates device special files for any new devices found on the system.
Reboot the system when it is required to correct the
inconsistent state between the kernel, and as used with the option. When used with the option, if there are no errors
associated with the instance reassignment, reboots the system.
Verify if there is any corruption in
ioconfig_file. If the verification of ioconfig_file is successful, the command displays a message showing if the type of
ioconfig_file is either legacy (for example, or agile (for example,
Note: HP-UX should not be rebooted without the file. If the file is missing or corrupted, HP-UX will recreate the file
before rebooting the system. If the system needs to be booted without the file (thus losing all the persistent I/O infor-
mation (see ioconfig(4)), the user can delete the file and reboot the system with the command (see reboot(1M)).

where infile contains the following:

To achieve circular reassignment of instance numbers between two existing devices of a class (specified in infile), assuming the driver
associated with the given hardware paths support online reassignment of instance numbers.
where infile contains the following:
is the h/w_path, is the class_name, and is the instance_#. The existing instance_# of this device is 30.
is the h/w_path, is the class_name, and is the instance_#. The existing instance_# of this device is 20. After the successful completion
of this operation, will have the new instance_# as 20 and will have the new instance_# as 30.
Verify file for corruptions and find if it is of type legacy or agile.
WARNINGS
Running or overwrites the effect of instance number reassignment by before the system is rebooted. The previous statement applies only for
devices whose drivers do not support online instance number reassignment.
