Using CVU to check for shared storage exceptions

Today, when using CVU to check for shared storage, there is a situation:

[[email protected] ~]$ cluvfy Comp ssa-n rac1,rac2-t data-verbose verifying gkfx storage accessibility Checking Share D Storage Accessibility ... Warning:prvf-7017:package Cvuqdisk not installed        

After the warning is not checked for shared storage, and then I install the package:

[[email protected] ~]$ cluvfy comp ssa-n rac1,rac2-verboseverifying gkfx Storage Accessibility Checking Shared St  Orage accessibility ... Disk sharing Nodes (2 in count)------------------------------------------------------ ------/DEV/SDB RAC2 Rac1 Disk sharing Node  S (2 in count)------------------------------------------------------------/DEV/SDC RAC2 Rac1 Disk sharing Nodes (2 in count)----------------------------------                                  --------------------------/dev/sdd rac2 Rac1 Disk                              Sharing Nodes (2 in count)------------------------------------------------------------/dev/sde RAC2 Rac1 Disk sharing Nodes (2 in count)------------------------------------------------------------/dev/sdf rac2 Rac1 Disk   Sharing Nodes (2 in count)------------------------------------------------------------ /DEV/SDG rac2 Rac1 Disk sharing Nodes (2 I               n count)------------------------------------------------------------/DEV/SDH rac2 Rac1 Shared storage Check was successful on nodes "RAC2,RAC1" verification of GKFX storage accessibility was suc Cessful.

So, cvuqdisk-1.0.7-1.rpm, what's this for? (Excerpt from:316817.1）

Cvuqdisk is applicable on Linux platforms only. CVU requires root privilege to gather information about the SCSI disks during discovery. A small binary uses the setuid mechanism to query disk information as root. Note that this process is purely a read-only process with no adverse impact on the system. To make this secured, this binary was packaged in the cvuqdisk rpm and need root privilege to install on a machine. When ' This ' is installed on all the nodes, CVU performs discovery and GKFX storage accessibility checks for SCSI D Isks. Otherwise, it complains about the missing package ' Cvuqdisk '.  You can disable the SCSI device check feature by setting the cv_raw_check_enabled to FALSE in $CV _home/cv/admin/cvu_config File. CVU won't complain about the missing RPM if this variable are set to False.

Truth!
