PowerShell cDot - How to Check Multi-Path and ACP

tomers — Sun, 21 Dec 2014 21:20:41 GMT

Hi Guys,

I want to check for each node in the cluster the status of the multi-path and the ACP.

Basically both lines appear one after the other in sysconfig output (node run -node * sysconig).

but I cant figure out how to get it from the powershell toolkit.

I can invoke-ncssh "node run -node currnode sysconig" but i am looking for a more suitable way to do it.

I don’t want to do string parsing if there is another option.

Any idea will be appreciated.

Thanks,

Tomer.

for ACP info, this might have what you need:

(get-ncnode | Get-NcShelfEnvironment).ShelfEnvironShelfList.alternatecontrolpathinformation

for the shelves, one way might be to check the disks for 4 paths (not sure if that covers all the possible edge cases):

get-ncdisk | where -Property paths -ne 4

Hi Mark,

Thanks for replaying.

*For the ACP, that is great. thanks.

*For the MultiPath, i thought on that but its tricky.

since you have too many options.

***NoPartner (Single) ***
DP = 1 Single Path
DP = 2 Multi path

***HA Pair***
DP = 1 Single Path
DP = 2
DP = 3
DP = 4 Multi path

But, using the ACP command you had found i found this:

(get-ncnode| Get-NcShelfEnvironment).ShelfEnvironShelfList.ConnectorInformation.SasConnectorList.IsCableConnected

i need to run a test on it in lab to see if i am correct, but assuming i do,

this check if the SAS cable is connected, and if all are connected then we have a multi-Path

if only one is connected the using the .ShelfModule (A/B) i can try to assume if i have a single-path or a mix.

Thanks,

Tomer.
