How can the timeout value for FC Switches be modified?
On a SAN having many Brocade and McData switches, increase the timeout value. By default, timeout
value for the switch is 3 minutes (in milliseconds). This value can be modified in the file FCSC.properties
available in the Lasso install directory.
How can the timeout value for Unix hosts be modified?
On a SAN having Linux, Solaris, HP-UX, and AIX hosts, the collection process may exceed the default
timeout value of 30 minutes (in milliseconds). Therefore, increase the timeout value in UnixHC.properties
file, available in the Lasso install directory.
How can the time out value for validating automatically discovered hosts be modified?
On a SAN having many attached hosts, increase the timeout value for the successful completion of
automatic validation in:
* SAC.properties— while automatically discovering hosts attached to arrays.
* WinHC.properties— while validating already discovered hosts in the background. This happens
when the customer configuration file is open.
What are the Storage Arrays supported by Lasso?
Lasso collects data from the following Storage Arrays:
* CLARiiON
* EqualLogic
* Celerra
* Power Vault MD Series
* EqualLogic Fluid File System (NAS)
* PowerVault Fluid File System (NAS)
How to collect data from EqualLogic Storage Arrays?
To collect data from EqualLogic Arrays in the SAN, install Lasso on a system that has access to the
array using the IP address. If the array is on a non-routable iSCSI network, then install Lasso on one of
the iSCSI server or add an additional system to the network to ensure connectivity.
FAQ — Passwords and Security
Why is password mandatory?
Lasso executes scripts that need access to administrative level resources. This requires remote login to
the systems to execute the scripts. Lasso does not save the entered passwords as it is captured from
the input and deleted after the connection. Blank password can also be used. The processes (net use,
putty, telnet and so on) that launch will prompt for the password . Enter the password multiple times for
each device. To avoid this, create a new user dedicated to run Lasso. This user can be deleted after
running Lasso. See
Readme
for more information.
How to ensure that the password is secured?
Search for a word or phrase used in your password in the c:\Program Files\Dell\Lasso file. Also, create a
specific user for Lasso that can be disabled after running Lasso.
Why should administrative Windows password be used?
The collection script EMCReports requires system access to obtain information about the system. See
the directory ftp://ftp.emc.com/pub/emcgrab/Windowsfor more information.
Why should UNIX Root password be used?
The collection script emcgrab requires root level system access to obtain information about the system.
See the directory ftp://ftp.emc.com/pub/emcgrab/Unixfor more information.
