Owner's Manual

Issue 20: Telnet must be enabled on all McData switches for Lasso to collect from them.
Issue 21: Lasso's "auto-discover" feature only works with EMC CLARiiON arrays, not for hosts attached to
Celerra, EqualLogic, and PowerVault MD Arrays.
Resolution: For those arrays, enter in the name or IP address of each attached host.
Issue 22: The SAN Configuration HTML document shows "unknown" in many areas as currently very little
information is collected from VMware and 64-bit Linux hosts attached to CLARiiON or Celerra.
Issue 23: spcollect command is not supported on EMC Arrays having FLARE less than R13.
Resolution: Run the command "getall".
NOTE: This command provides only a small amount of information.
Issue 24: To run Lasso, command line JRE Version 1.6 or above is required.
Issue 25: Lasso installer does not support SystemRoot directory as a destination folder so do not choose
this directory as the destination folder for Lasso's installation.
Issue 26: When Lasso is run from a Windows 7, Windows Vista, Windows Server 2008 or R2, if the User
Access Control (UAC) is turned on, the MD Series data collection is not successful.
Resolution: Make sure the User Access Control (UAC) is turned off.
Issue 27: When Lasso GUI is opened and we uninstall through CLI, the system reboots.
Resolution: Ensure that Lasso’s User Interface is closed before trying to uninstall Lasso.
Issue 28: For Linux, number of Physical NIC's are displayed in the HTML file as opposed to number of iSCSCI
NICs.
Resolution: Refer to the raw data collection for the below mentioned attributes:
- Number of iSCSI NICs
- NIC Link status
NOTE: For RHEL6 Hosts, the additional parameters which need be viewed from the raw data collection file
are:
- TcpSegmentationOffload
- UdpFragmentationOffload
- GenericSegmentationOffload
- ModelOfNIC
- ManufacturerOfNIC
Corrected Problems
The following problems were reported in earlier releases of Lasso and have been corrected in this release:
CR497904: Lasso needs to carry the latest EMCRPTS and EMCGrabs.
Description: When vSphere and Linux host collection was done, using Lasso version 3.9.1 the system would
hang because the version (version 4.3) of Emcgrab_Linux was not compatible. When the latest version of
emcgrab_Linux (version 4.4) was manually copied and run, vSphere and Linux host collection was
successful.
DF499752: Lasso is not parsing all the vlan information in Cisco 3750 switch.
Description: Lasso is not parsing some of the vlan information.
Example: vlan information for SAN_Vlan_10.2.1.0\24, ESX_vlan_10.2.2.0\24, and Vmotion_vlan_10.2.3.0\
24 was present in the raw data collection but was missing in the output HTML report.
