Hi All,

Bit weird issue i'm facing.

I've written a powershell script to grab the RDM details. But all of sudden things stopped working.

when I digged dipper I see get-scsilun is failing.

I see different results.

I see it is working perfectly fine on one cluster and but on another cluster it is not working.

anyone has seen any such problems?

Thank you,

Preetam

With Great Regards,

Nope. They are all same.

In fact I have  three vCenter

vCenter A -all 5.1

Cluster A -Works

Cluster B -doesn't works

Cluster C -Works

vCenter B - all 4.1

Cluster A -doesn't works

Cluster B -doesn't works

I found out that this is happening because of PowerPath V/E.

When I run the same script against environment where there is no PowerPath V/E it works.

However results are not consistent as mentioned above.

On some hosts it works and on some hosts it doesn't

Even PowerPath V/E same across all host.

Hope it helps.

Hi ,

Can you try something like that.

In my case, i use this kind of script :

$hostname= "ESXHOSTNAME.LOCAL"

$esxLun = Get-ScsiLun -VMHost $hostname | where {$_.CanonicalName -ilike "naa.*"} |  select CanonicalName

Then my result.

CanonicalName

hi

as long as you work with PPVE the get-scsilun is not relevant

because get-scsilun check the value of MultipathPolicy and when you use PPVE its blank (shown as Unknown)

at the moment i working on PS1 script that marge EMC PP remote tools and PowerCli to get some results
