RecoverPoint/SE upgrade using Deployment manager

I am trying to upgrade recoverpoint which is at version 3.5 sp1 to 4.0 using deployment manager. but it fails with comment "system failed to verify fake wwns were done correctly"

Could any of you please elaborate on how WWN spoofing is done when we replace an RPA? and how can I find out if its done correctly

Resolved error by copying configuration from one of the RPAs to the rest .

Re: RecoverPoint/SE upgrade using Deployment manager

Faking the WWNs simply maintains the previous RPA HBA info on the new RPA via a linked file.

You can turn this check off via the relevant parameter in the DM config file.

Re: RecoverPoint/SE upgrade using Deployment manager

Hi,

You're getting this error since at one time, 1 RPA or more were replaced and the spoofing option (keeping the WWNs of the filed RPA) was selected.

To workaround this error, which means that the spoofing information wasn't synced between all RPAs, you would need to add the WWN details to all RPAs in the cluster, via boxmgmt.

Also, make sure to go to RP 3.5.2 before going to 4.0.2.2.

Re: RecoverPoint/SE upgrade using Deployment manager

So I cannot directly goto 4.0?

Re: RecoverPoint/SE upgrade using Deployment manager

Go to your DM directory and find the conf sub-directory. You will find the ndu.properties file. Open it and do a find for WWN. You will find a parameter called SHOULD_FAIL_ON_FAKE_WWNS_CHECK. Set this to false and then restart DM to perform the upgrade.
