Alan - You're very welcome. (I appreciate points for helpful or correct answers.) I'm still thinking you have an igroup problem here. I think the igroup that the LUNs are mapped to on the NetApp still have the old iqn for the windows host. You don't mention whether you're trying to use command line or System Manager here. Nor do you mention where/how the 'NetApp does see the iqn' ? Clicking 'Quick Connect' in the targets tab won't get you there if the igroup doesn't have the iqn there. You may wish to take a look at the iSCSI Configuration and Provisioning for Windows Express Guide in NetApp documentation. I hope this response has been helpful to you. At your service, Eugene E.

Dhakshinamoorthy - There're numerous factors that will affect CPU. You can look at which domains of Data ONTAP are using CPU with the advanced 'statit' command, and 'sysstat' with the -M flag.

Robert - The documentation line was from the 'aggr options' section of the man page. It was 7-mode 8.2 documentation. What version are you running ? There's also the following under 'aggr add' on the man page: The -t raidtype argument specifies the type for new RAID groups created when adding disks to the aggregate. Use this parameter when you add the first RAID group comprised of SSDs to a hybridenabled aggregate. Possible values are raid4 for RAID 4 and raid_dp for RAID DP. The default value is type of existing RAID groups of the aggregate. That would imply that raid4 could have been set when first adding the SSDs to the aggregate. I was wondering the same thing about changing the whole aggr to raid 4, then just changing the HDD disks back to DP. Cautious ? Is this system already in production ? I was hoping it wasn't yet, and you could try the rebuild ... I hope this response has been helpful to you. At your service, Eugene E.

Robert - The documentation example you gave was for Cluster mode, as was the simulator I tried it on. The 7-mode documentation seems to indicate it can be done there, too. From the 'aggr' command man page in 8.2: "The -T parameter can be specified to change the RAID type of the HDD RAID groups or the SSD cache of a Flash Pool. To specify the SSD cache, use -T SSD. To specify the HDD RAID groups, specify any Data ONTAP disk type used in the HDD RAID groups of the Flash Pool. " I hope this response has been helpful to you. At your service, Eugene E.

Robert - You seem to be correct in your thinking. You should be able to change the raid type of just the SSD tier to raid4, and given your small pool of available drives, I would do so. It seems a waste of expensive SSDs otherwise. SSDs have a lower rate of failure, and you have a lower chance of failure given the small number of drives, so would be worried about not having DP protection there. I've tried it on my lab simulators, and it worked just fine. I hope this response has been helpful to you. At your service, Eugene E.

Sanjay - You could put them on the same loops, given that they're both 6G shelves. Best practice would be to use separate loops for SATA and SAS shelves.

Claude - It's not going to work the way you're thinking about it. The closest native solution with NetApp would be a Metrocluster install, as Radek mentioned above. The most common Oracle solution for DR is using Oracle Dataguard to do the replication between sites, though there are SnapMirror fail over scenarios, too.
