Owner's Manual

This readme contains information for Lasso 4.2.
Lasso is a Java-based utility that automates the collection of logs and configuration from servers, disk arrays (EqualLogic,
PowerVault MD-Series, and EMC), Fibre Channel switches (Brocade, McData, and Cisco), Tape Libraries, and Ethernet and
FCoE switches.
After the collection, Lasso parses the data into an XML file, which is packaged with the original collection and encrypted.
The encrypted file is uploaded to Dell Technical Support to use the hardware, software, and firmware information for
troubleshooting, checking compatibility, and upgrading existing equipment.
What’s New
1) Support time out value option for Windows host. Collection on Windows host is automatically terminated if the host
times out.
2) Support for automatic upgrade to new version of Lasso using GUI or CLI without uninstalling the current or earlier version.
3) Support for firmware version 6.0 (Glenlivet) on Dell EqualLogic Arrays.
4) Enable the following methods to automatically upload the report to Dell Technical Support site:
 Authenticated Proxy
 Non-Authenticated Proxy
 Pass through Authentication

6) Parser support for the following devices:
 Dell M1000 Enclosure
 Dell Blade Switch M8428-k (Brazos)
 Storage Array MD3600i (FatBob)

Advanced Server Program (BASP) software.
8) Support to parse Converged Network Adapter (CNA) card information using Broadcom command Line Utility (BCU)
installed on Windows Hosts attached to EqualLogic, MD Series, and Compellent.
9) Support to collect and parse Host Integration Tool Kit data for VMWare hosts in the EqualLogic, MDSeries and Compellent
SAN using Management and Monitoring screen in Lasso user interface.

EqualLogic, MD Series, and Compellent.

 Large_Frames
11) Support to collect VMware support logs in case of EqualLogic, MDSeries, and Compellent SAN using advanced mode.

13) Time and speed used to perform the “Ping test” to test the connectivity between the EqualLogic devices is the same as
used by Putty.
14) Support to collect diagnostics information from Cisco Nexus switches.
15) Support to collect and parse the value for the “TCP Delayed ACK” Windows setting from Windows Host attached to
EqualLogic, MDSeries, and Compellent SAN.
16) Provide Ethernet Switch Type as,
 “ PowerConnect ” - collect and parse all the Power Connect switches and PowerConnect M8428K. Only collect for
all PowerConnect B8000 switches
 “ Brocade Ethernet ” - collect for all Brocade B8000 switches
17) Display the build version of Lasso used for collection on the top of the HTML report.
18) Provide the error code and the message when process fails during collection, parsing, or report upload for a SAN device.
19) Collect and parse the output from “esxcli iscsi networkportal list" command of the iSCSI Network cards for VMware
