Rescan All Hba’s Where are you?

Posted on June 17, 2009 by Jon Owings

So I was updating some of my blog posts on the esxcfg-* commands with any changes in ESX 4. I wrote earlier I did not know much about the esxcfg-advcfg command. Since writing that post at the end of 2008, I found Duncan Epping used esxcfg-advcfg in 3.5 to set the option rescan all the Hba’s. I thought this was a great shortcut and decided to try it out in vSphere but:

[root@esx4 ~]# esxcfg-advcfg -s 1 /Scsi/ScsiRescanAllHbas
Exception occured: Unable to find option ScsiRescanAllHbas

So I looked through vCenter 4 and did not find the option under Scsi I looked around some in the other Advanced Options and it is no where to be found.

Has this been removed or moved somewhere else? If you know hit me up on twitter @2vcps

    You can take a look at this script which allows you to rescan all hosts within a specified cluster.

    That is very cool. It would be nice to have the Advanced Option though, so it can be done in the vSphere Client.

    I am sure there is a downside to rescanning everything especially in big enviroments.
