Help with Multipathing and snapdrive over FC

venarcnetapp — Thu, 05 Jun 2025 07:16:15 GMT

Hi,

I am using RHEL5 update4 and I have configured multipathing. I am not sure what to use in the snapdrive.conf file for the following:

#multipathing-type="none" # Multipathing software to use when more than one multipathing solution is available. Possible values are 'NativeMPIO' or 'none'

do I leave it to none or change it to Native MPIO?

Thanks,

Leo

Hi,

Firs thing first, have you configured /etc/multipath.conf file ?

for snapdrive.conf file you provide the Multipath technology you are using natively. By default it is NativeMPIO which gets used.

Hi,

Yes I have, for device I've selected NetAPP. Since the snapdrive config is commented out, based on your response, I assume NativeMPIO is being selected as default.

Thanks,

Leo

Yes, if it is commented out.

But you can uncomment it if you want it to use MPIO settings. Do refer the Admin guide in doing so.

Also to verify if currently snapdrive is using mpio you can test it by creating a lun directly and check the multipathing using 'multipath -ll' it will list you active paths for that particular storage.
