1. You will likely be adding shelves online, in which case nothing bad happens. You will see new foreign aggregate that you simply immediately destroy after that. 2. I doubt that having 10K and 15K on the same loop will have any measurable impact by itself. But 10K are likely 2Gb/s disks and 15K - 4Gb/s disks, which means, you will need to run the whole loop with 2Gb/s. Actually, if FAS3240 runs 8.1, 2Gb/s components may simply be out of support now; you have to carefully check system configuration guide. ... View more

There really should be a FAQ somewhere Once block is allocated to a LUN, it remains allocated on NetApp even if operating system later marks it as "free". So one host at some point had 2.6TB of data on a file system on the LUN. That now excess data are deleted in file system does not make blocks that once contained deleted data available for NetApp. If you are using SnapDrive, you could try space reclamation to return free space on file system to NetApp free space pool. ...

I remember post on communities that described how to add additional disks to simulator. I do not have link handy, sorry.

No, you have to run tests for all individual devices on motherboard. The following is currently recommended after motherboard replacement: These devices need to be disabled: 'sas', 'fcal', 'nic', if present, 'acpm' and 'pam2/fcache'. So you basically take default list, disable tests for above devices if present and run diagnostic. ... View more

It is misunderstanding where fragmentation comes from. Let’s say you have file with contiguous blocks 1,2,3,4,5,6. Now 2,4,6 are overwritten. Maybe in the same CP timeframe. So you are left with 1,hole,3,hole,5,hole contiguous 2,4,6 So file is fragmented; there are no two blocks located contiguously. Even though there was enough space to write new blocks sequentially. It is hard to say whether read_reallocate will help. It happens in the wrong time (i.e. - first data is accessed and only then it is reallocated). So it is dependent on workload; but it will create permanent additional disk load which is again hard to quantify. Try to run reallocation more often, may be every day before backup, and to check whether it has noticeable impact on your system. Official statement is, reallocation scan runs in background and has low priority. I have seen multiple people saying they did use it during normal working hours without any performance impact. Or consider dropping tape backup in favor of snapmirror/snapvault. May be consider offloading tape backup to snapmirror/snapvault destination. This will allow you to reallocate destination without impact to source and be more flexible with backup window. ... View more
