VI Toolkit Commandlet or script to report HBA path status

[chayes]

This might be an obvious question (I'm new to this forum)...

Does anyone have, or is anyone aware of a VI toolkit commandlet or script to easily report on the status of physical (and logical) storage paths between ESX hosts and storage devices WITHOUT installing a host-side agent? I realize that storage vendors provide reporting mechanisms from the storage infrastructure end, but given the importance of paths to storage in the VM space, I see this as essential tool from an VM Admin's perspective--independent of what the storage infrastructure is telling me. Any feedback would be appreciated. If you could point me to a canned solution, all the better

Thanks!

Could you perhaps elaborate a bit on what exactly you want to report.

Is it static reporting, for example every day, that shows the storage paths ?

Or do you want more dynamic reporting, for example an alert when something diverts from your desired configuration ?

There have been some discussions in the VITK community on storage paths.

You could perhaps do a find on some of the obvious terms (hba, WWN, lun, scsi, active path...)

Not sure if this is what you looking for or not, but I wrote this when I needed to check out our configuration. Be aware that for real time updates this may not work well because of the nature of the vpxa agents. I am going to look into calling a Refresh on the details before I collect the data. This is much like you have to click refresh in the VI Client to make sure you are getting up to date information.

connect-viserver <host or VirtualCenter>

Get-Host | .\DetailedLunPathInfo.ps1

1. or Get-Cluster <clustername> | Get-Host | .\DetailedLunPathInfo.ps1

To save you can always | Export-Csv <report filename>

Yeah, this is kinda what I'm talking about as it includes the path status, which is the primary need. Worded very basically (LucD wanted some clarification), I need to know when storage paths are down; active or otherwise. And again, I'd rather have the means to get this from the Virtual Infrastructure perspective (rather than the storage side). The refresh or static data topic is not really an issue as I would simply schedule the report.

Perhaps also have a look at the script in .

That shows perhaps what you're after.
