Hi M.Sultan,
Please perform the following steps:
Step 1. Run the dir flash: command.
Step 2. Identify one of two file types to boot the switch. The two types are:
A bootable binary image file (denoted by a.binfile extension) for Catalyst 9000 Series Switches. This file can be seen as: cat9k_iosxe_<majorversion.minorversion.releasenumber>.SPA.bin
Note: Catalyst 9200 Series switches do not use the same universal image as current 9300, 9400, 9500, and 9600 Series switches. A Catalyst 9200 Series switch binary image has a similar file name convention to: cat9k_lite_iosxe...SPA.bin
A bootable configuration (.conf) file that specifies packages that were previously extracted from a relevant bundle file. To boot this file type, you must also have specific package (pkg) files in flash.
Note: This guide does not cover the operational differences between these two boot methods, known as bundle mode and install mode. In a switch stack, boot modes must match across stack members. For applicable platforms, a stackwise virtual pair must run in install mode. Run the command show version from the exec prompt to determine the current boot mode of an operational switch stack.
Example of a .bin file which can be used to boot the switch into bundle mode:
switch: dir flash:
<snip>
cat9k_iosxe.16.12.04.SPA.bin
Example of a .conf file with packages in flash. (The next step describes how to verify that these are the correct packages.)
switch: dir flash:
<snip>
14464008 -rw- cat9k-cc_srdriver.16.12.04.SPA.pkg
89134084 -rw- cat9k-espbase.16.12.04.SPA.pkg
1684484 -rw- cat9k-guestshell.16.12.04.SPA.pkg
531063808 -rw- cat9k-rpbase.16.12.04.SPA.pkg
41799673 -rw- cat9k-rpboot.16.12.04.SPA.pkg
31478788 -rw- cat9k-sipbase.16.12.04.SPA.pkg
60392448 -rw- cat9k-sipspa.16.12.04.SPA.pkg
23217156 -rw- cat9k-srdriver.16.12.04.SPA.pkg
7560 -rw- packages.conf <-- .conf file calls a group of packages
12907520 -rw- cat9k-webui.16.12.04.SPA.pkg
9216 -rw- cat9k-wlc.16.12.04.SPA.pkg
Step 2a. If you choose to boot a .conf file, you must have the correct associated packages in flash. A failed boot of this type can indicate package corruption or an incorrect "conf file for the packages in flash.
To verify if you have a conf file that matches the packages contained in flash, issue cat flash:<filename>.conf and replace <filename> with the relevant package configuration file name. In this case, the file is called packages.
Note: The default name for a package configuration .conf file is packages.conf. Some upgrade procedures can result in different filenames.
Text output of packages.conf, which indicates what .pkg (package) files are needed in the flash file system for the switch to boot properly:
switch: cat flash:packages.conf
#! /usr/binos/bin/packages_conf.sh
sha1sum: fb7ea5ea75a0cbf14ce81cecf110e5a6d526df86
# sha1sum above - used to verify that this file is not corrupted.
#
# package.conf: provisioned software file for build 2020-07-09_21.53
#
# NOTE: Editing this file by hand is not recommended.
<snip>
# This is for CAT9k
boot rp 0 0 rp_boot cat9k-rpboot.16.12.04.SPA.pkg <-- package files are for version 16.12.4
iso rp 0 0 rp_base cat9k-rpbase.16.12.04.SPA.pkg
iso rp 0 0 rp_daemons cat9k-rpbase.16.12.04.SPA.pkg
iso rp 0 0 rp_iosd cat9k-rpbase.16.12.04.SPA.pkg
iso rp 0 0 rp_security cat9k-rpbase.16.12.04.SPA.pkg
iso rp 0 0 rp_wlc cat9k-wlc.16.12.04.SPA.pkg
iso rp 0 0 rp_webui cat9k-webui.16.12.04.SPA.pkg
iso rp 0 0 srdriver cat9k-srdriver.16.12.04.SPA.pkg
iso rp 0 0 guestshell cat9k-guestshell.16.12.04.SPA.pkg
<snip>
Step 3. Issue either the boot flash:<filename>.bin command or the boot flash:<filename>.conf command with the proper <filename>.
switch: boot flash:packages.conf
boot: attempting to boot from [flash:packages.conf]
boot: reading file packages.conf
