chargeback by group reporting
Hello,
I wonder if anyone has encountered these issues before. We have a new SRM deployment, standard 4 VM vApp deployment plus an extra vApp collector running version 3.6.2.
Reporting on heterogeneous storage, VMAX, VNX, HDS, NetApp with Brocade switches
Several customers spread across these arrays, all connected with the same SAN switches.
We are particularly interested in the Chargeback reporting so enabled passive reporting in both Brocade and HDS data collection.
A device group has been created per customer which lists the required hosts, the chargeback report produces a line for each group but the figures are wildly out.
Two issues, when drilling down to each host listed for a customer there is more than one entry for each host. Host alias from the switch zone name and from the array solution pack are not identical so the chargeable figures are halved.
Also some of the LUNs sizes are not shown. This happens a lot for ESX clusters some of which are using block NetApp storage. Some, not all the NetApp LUNs have no size listed.
Cheers

Hello Wayne,
From your description it is not seem like you have enabled active discovery of hosts in your environment but please confirm.
If the above statement is true and if the duplicate entries are caused by hosts being deduced by Brocade and Hitachi SPs, I would suggest that you disable passive host discovery via Hitachi SP since Hitachi SP only picks up hosts defined in the Hitachi Device Manager which is a very limited set anyways. Moreover, it looks like these hosts (connected to Hitachi arrays) are following the naming convention resulting into they being deduced from the Brocade SP so you are not losing any info.
For the NetApp issue, we would have to look at the collection logs, it’s difficult to comment on that without additional info. Please open a SR for this.
I hope this helps.

Thanks Gayatri,
It looks like the Hitachi and Brocade have recorded the host names slightly differently that explains why the hosts are appearing in the storage reports more than once.
I'll raise a call about the missing LUN sizes in the charge back drill down report
