User's Manual

– Lasso initiates scripts against all defined devices. The scripts collect specific information about the
devices. Lasso then captures the output of individual process separately for each device. This helps to
simultaneously complete the collection. If the time taken for manual login, copy collection
(example:EMCReports) for a host is 5minutes, Lasso can collect data against 10 hosts for the same time.
NOTE: The limit for simultaneous processes is 10. The limit can be modified in the LassoConfig.xml
file.
• What is the time taken by Lasso to run?
– The time taken is approximately 30 minutes for a normal run. Many factors can modify the estimated
time. The approximate time is determined by adding the following:
* Time taken to input profile and environment information (dependent on the user).
* Time taken to copy EMCReports/emcgrab to the remote device (less than 2MB file size. It is fast
on a LAN but slow if remote).
* Time taken by the longest device. It is 5-10 for hosts, but may be over 20 minutes on a busy host.
For SPCollects, the time taken is approximately 10 minutes, but on a busy SP it is 30 minutes or
higher. For switches, less than 5 minutes, but on large switches with error logs, may be 20
minutes or higher.
* Time taken to copy the collection data from the remote device (may be fast on a LAN but slow if
remote).
* Time taken to zip and encrypt the data (may be less than a few minutes).
* Time taken to upload the data to Dell's FTP site (may be the longest time depending on the size
of the environment and the speed of the Internet connection).
Using the above guidelines, assuming that the profile and environment information is already entered, all
devices are on a LAN, the longest device takes 15 minutes, a few minutes to zip/encrypt, and the
Internet connection is fast, the entire collection should be completed in less than 30 minutes.
If there are environment specific settings that prevent remote execution of some of the scripts, then
troubleshooting may take more time.
• What is Navisphere CLI and where is it available?
– Lasso uses EMC's Navisphere CLI to initiate commands to CX and AX Storage Processors. Among these
commands are SPCollect, getall, and getlog. Navisphere CLI is available at http://powerlink.emc.com
and also provided with the Lasso package.
