You have one spare disk. Spare can be used for smaller disks as well. So what I said before still holds: physically replaces 500GB spare with 1TB spare run "disk replace" to swap 500GB disk in bigaggr with 1TB spare. This will leave you with 500GB spare again physically replace 500GB with one more 1TB disk This will leave you with one 1TB spare suitable for both aggr0 and bigaggr.   If you have possibility to do so, I'd consider moving content of aggr0 to bigaggr, replacing 500GB disks with 1TB disks and adding them to bigaggr. This would improve space utilization and resiliency and may give slight performance boost. ... View more

1) After the rebuild is completed, will following line in aggr status disappear? And can I see the remaining progress status of rebuild when it is rebuilding?   data FAILED N/A 847555/1735794176 Yes to both. Failed disk won't be part of aggregate anymore and you can see percentage in aggr status -r.   2) I know that 500GB disk in this aggregate is not a suitable size. But is it functioning for this aggregate? Unfortunately, yes. Which is why you cannot remove it.   You metioned I should run disk replace command to move the 500GB disk to new 1TB disk, but I don't have empty slot anymore after I add a new 1TB disk to bay 0c.00.10. You still have failed disk. You should now remove it, it will give you free slot. Or have you already done it? Please show full "sysconfig -r" output. ... View more

Because of the predetermined nature of the paths, it is not a simple matter to move a WWN from port C to port D on storage.  Consider that the WWN is logged into the switch on a particular port. Sorry have to chime in here. Moving WWN to different port is easy and does not cause any problem to hosts. But this does complicate implementation on storage side. Today multipath stacks are ubiquitous in operating systems, so it is easier to rely on them than implement it in storage. But there are no inherent lilmitations of FC that would make different implementation impossible. If you remember, NetApp had used WWN relocation in the past. It actually worked 🙂 ... View more

Only cluster built with HA pairs is supported (with sole exception of single-node clusters). Technically cluster itself does not care - you can build cluster with multiple non-HA nodes, e.g. simulators. In this case you obviously lose storage if node fails. I have not used simulator for ages (too much resources needed) so I do not know if it supports C-Mofe HA now. ... View more

3)After zeroing finish, I run "aggr add bigaggr -d 0c.00.10" to add the spare disk to this aggr. Then rebuild will be started. Is my thinking and procedure correct?   NO! You do not replace failed disk by adding disk to aggregate. And I'm rather surprised nobody mentioned this before.    There is no command to manually initiate rebuild. Rebuild is started as soon as spare disk of suitable size is available. In your case it did not happen becuase you did not have matching spare disk.   What you should do now is add new spare disk of 1TB in size. Do not add disk to aggregate! wait until rebuild is completed physically replace failed disk with yet another 1TB disk. Do not add disk to aggregate run disk replace command to move 500GB disk to new 1TB disk remove 500GB disk and add one more 1TB disk as spare This will leave you with healthy aggregate (expanded by one disk) consistng of 1TB disks and one more 1TB spare which will be used next time disk fails.   If you do not want to keep aggregate expanded, your only option is to move/copy data, destroy and recreate aggregate and copy data back. ...

Max supported number is 6 shelves per loop. I do not know if exceeding it can cause problems. Start with single shelf per loop and add shelves one by one making sure configuration is stable each time.

It speaks about outgoing connections (such as DNS, LDAP, NTP etc).

Previous versions required that suitable LIF was present on node that initiated connection. ... View more

For NFS 4.x it is possible to use referrals or pNFS. Both require client support; referrals redirect open request to the optimal node, while pNFS can dynamically change optimal access path.   CIFS supports DFS referrals as well; similar to NFS it happens once on initial open.   You can find more information in NFS or CIFS Management Guides.   But note that while indirect access may be slower, it does not automatically mean your clients actually notice it for your specific workload. So you should first try to estimate impact of indirect access before trying to optimize for it. ... View more

I tend to miss the fact that in ESX virtual machine definition can still reside on a single datastore only. So if this datastore is lost, you lose your virtual machines.
