Settig Multiple LUN's to Fixed and specifying the PerferredPath

[ChristianNilsso]

Hello Community.

I need to set my LUN's back to Fixed and spesify the perferred path.

I can't seem to get the command to work.

Get-VMhost | get-scsilun "lunname" | Set-ScsiLun -MultiPathPolicy "Fixed" -PerFerredPath "pathname"

The line works fine on RoundRobin and MRU. But when i insert "Fixed" i calls out for a Perferredpath, witch it does not accept.

Any cloues to where i fail?

Did you use a LunPath as returned by the Get-ScsiLunPath cmdlet ?

Get-VMhost | get-scsilun "lunname" | Get-ScsiLunPath

I tryed that. the get-scsilunPath returns our 4 paths, 50:01:43:80:01:3C:80:CC

50:01:43:80:01:3C:80:C9

50:01:43:80:01:3C:80:CD

50:01:43:80:01:3C:80:C8

In my case, I whant :C8 to be the perferred. So the command looks lite this:

Get-VMHost | Get-ScsiLun CannonicalName | Set-ScsiLun -MultiPathPolicy "Fixed" -PerferredPath 50:01:43:80:01:3C:80:C8

It returns: A parameter cannot be found that matches parameter name 'PerferredPath'

Perhaps it's just a typo in the thread but the parameter is -PreferredPath, not -PerferredPath.

The string you give as the path looks more like a SanId to me.

Are you sure that is the value you see in the LunPath property after

Get-VMHost  | Get-ScsiLun -CanonicalName <name> | Get-ScsiLunPath | select *

Yes.

I missspelled.

And it was the Scsi ID not the complete path name.

now it works, just need to find a way to make ti work on 8hosts (dif path name) and about 40 LUN's

Thx a lot.
