iv Scripting WS-MAN Firmware Updates

Introduction

WS-MAN provides secure, simple, scriptable, and standards-based remote management capabilities
on Dell PowerEdge servers equipped with iDRAC.

WS-MAN is a network transport service that enables a user to access a number of Common
Information Model (CIM) data access and methods supported by the target platform. WS-MAN can be
scripted using command line interfaces (CLI) such as WinRM on Microsoft® Windows® systems and
WS-MAN CLI on Linux systems.

This document uses the Python scripting platform, which run son both Windows and Linux systems.
Some additional reading of specification documents may be required to understand the terminology
and concepts in this paper.

In this document, you will learn how to:

• View firmware information/inventory on a system.

• Perform a firmware update.

• Perform a firmware rollback.

Before You Begin

Before you begin, it is recommended to take the following actions:

1. Make sure the target system is a PowerEdge server with iDRAC enabled, configured, and
network accessible to communicate with WS-MAN.

2. For Windows, make sure the WinRM command line tool is configured and ready (for help, see

Installation and Configuration of Windows Remote Management

For Linux, make sure the Openwsman CLI is built, installed, a nd read y (fo r help, go to the

Openwsman Home

3. Make sure Python 2.7 is installed on the target system (for help, see Python Home).

4. Download the following Python scripts:

a. [fw_inventory.py]
b. [fwupdate.py]
c. [fw_poll.py]

and join the mailing list).

Figure 2 shows an example of the target environment. It starts with the administrator (1) running
scripts to send WS-MAN commands through an SSL connection. The target system (2) is equipped with
iDRAC, which is a management controller with advanced capabilities. The update repository (3)
contains the Dell Update Packages (DUPs) that will be used to update the firmware on the target
system.

Performing a firmware update

The remote firmware update process involves the following steps

1. View the current firmware inventory of the system

2. Begin the update process

3. Monitor the update process

6 Scripting WS-MAN Firmware Updates

9 Scripting WS-MAN Firmware Updates

Once the firmware inventory is listed, you can either continue with the firmware update or quit.
To perform a firmware update, select one of the options that are available for update.

The script will prompt for the location of the Dell Update Package (DUP) to be used. iDRAC
supports the following download methods with source URI syntax:

• FTP
ftp://[IPADDRESS]/[LOCATION]/[DUPFILENAME]

• HTTP
http://[IPADDRESS]/[LOCATION]/[DUPFILENAME]

• TFTP
tftp://[IPADDRESS]/[LOCATION]/[DUPFILENAME]

• CIFS
cifs://[USER]:[PASSWORD]@[IPADDRESS]/[LOCATION]/[DUPFILENAME];mountpoint=[MOUNTN

AME]

• NFS
nfs://[IPADDRESS]/[LOCATION]/[DUPFILENAME];mountpoint=[MOUNTNAME]

The all-caps portions of the syntax represent user-provided values. The [IPADDRESS] is the IP address
of the update package repository. The [LOCATION] is the path or dire cto ry. The [DUPFILENAME] is the
update package file name; the only supported update package is the “Dell Update Package for
Windows” that can be downloaded from support.dell.com. [USER] and [PASSWORD] refer to the user
credentials required to access and download files from the share. [MOUNTNAME] refers to the share
mount name.

Sample output:

Options

tftp://192.168.0.100/BIOS-2011.exe

nfs://192.168.0.100/BIOS-2011.exe;mountpoint=/pub

cifs://DOMAIN\\USER:PASS@192.168.0.100/pub/BIOS-2011.exe;mountpoint=E

http://192.168.0.100/BIOS-2011.exe

ftp://192.168.0.100/BIOS-2011.exe

Enter the path of the image file: tftp://192.168.0.3/DUP.exe

6.

The script will prompt for a reboot type that the host will use reboot before performing the
update. Select an appropriate reboot type.

Reboot Type Options (1,2,3, and 4)

10 Scripting WS-MAN Firmware Updates

1 = Forceful shutdown and reboot

2 = Graceful shutdown and reboot (Recommended)

3 = Forceful shutdown if graceful shutdown does not succeed

4 = No reboot

7. The script asks for permission to delete all existing jobs in iDRAC. It is recommended to choose yes
for a clean start.

Erase all previous jobs stored in the iDRAC? (yes/no) yes

Deleting all iDRAC jobs

Completed job deletion

8. The script requests a start time for the job. The job can be scheduled immediately or for a future
time.

Schedule the nic update now or schedule later (now, schedule)? now

The format of the StartTime argument is defined by the CIM Infrastructure Specification.
Enter now to schedule the jobs immediately, or enter schedule to schedule the job for a
future time. The schedule option will prompt for a start time, which you must enter in the
format MM-DD-YYYY hh:mm:ss

Y = Year, M = Month, D = Day, H = Hour, m = minute, S = second

12-13-2011 11:11:11

Once the start time is specified, the update job is initiated.

The update package is downloaded from the repository. This may take some time depending on the
size of the package and network state. After the update package is successfully downloaded, the
update and the reboot job are scheduled for the specified start time.

Sample output of successful command:

nic update successfully created

Creating reboot job

Reboot job successfully created.

Scheduling nic update job

Scheduling reboot job

The nic updating from version 7.0.21 to version
ftp://10.35.155.122/Release_DUPS/Network_Firmware_JXJWY_WN_7.0.46_X36.EXE

11 Scripting WS-MAN Firmware Updates

Check the status of the reboot job and the nic update job by using the fw_pull.py

script.

Sample output of failed command:

The command failed with error code: CMPI_RC_ERR_INVALID_PARAMETER

If the command fails, check that the InstanceID you provided is accurate by comparing it with output
from the previous step. Remember that characters are case sensitive. Also, check the accuracy of the
source URI to ensure it is accessible with proper permission. Once verified, try the command again.

After the specified start time elapses, the host reboots and launces System Services to perform the
firmware update.

Monitor the update execution

The final step in the update process is to monitor when the update executes, and then to verify the
update by checking the new version from the inventory enumeration.

1. Run fw_poll.py –h for usage options

./fw_poll.py -h

Usage: fw_poll.py [options]

Options:

-h, --help show this help message and exit

-j JOBID, --JobID=JOBID
Provide one of the JobIDs (begins with JID or RID)
within the fwupdate.out file

-v, --verbose Prints information verbosely

2. Enter requested information:

Enter iDRAC IP Address: [iDRAC IP]

Enter User Name: [USER NAME]
Enter User Password: [PASSWORD]

1. The first argument is the IP address of the iDRAC on the target system. The second argument is
the user name; if the user is an Active Directory account, then the syntax is USER@DOMAIN. The
third argument is the user password.

Sample output:

Available JobIDs.

(1) JID_267336093962

- nic updating to image located at

ftp://10.35.155.122/Release_DUPS/Network_Firmware_JXJWY_WN_7.0.46_X36.EXE

(2) RID_267336106745

12 Scripting WS-MAN Firmware Updates

- reboot for nic update

(0) exit out

Enter a number to poll JobID or to exit. (1,2,etc): 1

JobStatus = Scheduled

Message = Task successfully scheduled.

MessageArguments = NA

MessageID = JCP001

Name = update:DCIM:INSTALLED#701__NIC.Integrated.1-2-1

Repeat get JobStatus command for JID_267336093962? (yes, no):

3. Select the number corresponding to your job to display the current status.
The script performs two step executions. The first step is to monitor the status of the job associated

with the update. When it detects the status is completed, it monitors the status of the data sync. At
this time, the update has been executed and the device is running the new firmware level.

Performing a firmware rollback

A firmware rollback applies a device’s previously installed firmware version. This is useful when you
encounter a new firmware level that was just updated and is causing problems or incompatibilities in
the system.

To determine if firmware can be rolled back, examine the inventory list and look for “available” in the
status. For example:

5(update) FRMW Installed None 7.0.47 Broadcom Gigabit Ethernet

BCM5720 - 18:03:73:0F:45:48

To perform a rollback, select the firmware entry marked “available” and run the update script without
the source URI. The script will detect that the request is a roll back and will execute the proper
commands. Unlike an update, a rollback does not go through the download phase. Jump to scheduling
the update and follow the rest of the process.

Sample output:

./fwupdate.py

Enter iDRAC IP Address: 10.36.0.117
Enter User Name: root
Enter User Password:
Pinging 10.36.0.117. Waiting for response. Done.
Certificate exists!

14 Scripting WS-MAN Firmware Updates

Exceptions

One exception to the process described in the previous sections is that certain updat es do not require a
reboot and scheduling. After the update package is downloaded, it is immediately applied to the
device. This exception applies to Lifecycle Controller, Diagnostics, and OS Driver Pack firmware
updates. System CPLD Updates are currently not supported by this method.

Summary

In this paper, you have learned how to perform an inventory of firmware installed on your system, a
firmware update on select system devices, and a firmware rollback.
