Comment on ZFS migration using incremental send/receive by Bjoern Rost

Thanks for mentioning that. zp04 was another pool that I migrated on the same box but I guess it is confusing to have it in the example so I modified it.

I think you introduced zp04 without explaining where it is coming from. A typo maybe?

Hi,
nice work.
i have a T4-2. as you said there are 2 pcie buses.
when i divide the both pcie buses into 2 domain.
like pcie0 to control domain and pcie1 to alternate io domain.
i just need to know that which pice slots will be connected to pice bus0 and which slots will be connected to pcie bus1??

yes, in this example, I only assigned a single endpoint device to my ldom. One could also assign a whole PCIe bus (that feature has been included for a while) but I did not want to do this in this case. The primary ldom boots from disks on an HBA that is also on one of those busses and I also preferred to virtualize the NICs in the primary domain.

hi
IMHO, younuse the pcie bus too lossely
in your example, you assign pcie slots(end point) to the io-domain , not the pcie bus

Pluggable and Data Guard Far Sync are my most preferred picks of the lot. Orable 12c Database features have opened up a world of opportunity to bloggers.

Comment on Flex Everything in Oracle RAC 12c by favourite Oracle 12c database features of OpenWorld Bloggers | portrix systems

[...] Jason Arneil (@jarneil) loves Cluster ASM for the fact that it will be possible to have multiple ASM instances running on the same system. The concern is that when you consolidate databases they all become dependant on only one ASM instance. And if that one has issues, all databases on the system will get taken down with it. Apparently, the problem is big enough that people were already fiddling with this in 11g and managed to start multiple ASMs even though it is not supported. (update 2013/04/14: blogged about it) [...]

Hi Peter,

exactly. That failover is the whole point of flex asm. So it increases availability in cases of crashes (or planned outages) of ASM instances.
