Etherchannel LACP support?

Looney128Oct 11 2012 — edited Oct 15 2012
Now that I got my ISCSI working..... and now have it with ALB bonded with two ports. (ALB works)

Figured I would get better performance using Dynamic Link Aggregation.
So I set the bond to Dynamic Link Aggregation.

I also set my Cisco 6509 to....

Interface Port-channel4
description OVMS2_stor
switchport
switchport access vlan 2
switchport mode access

interface GigabitEthernet3/22
description OVMS2_stor
switchport
switchport access vlan 2
no ip address
spanning-tree portfast
channel-protocol lacp
channel-group 4 mode active

interface GigabitEthernet3/30
description OVMS2_stor
switchport
switchport access vlan 2
no ip address
spanning-tree portfast
channel-protocol lacp
channel-group 4 mode active


I do not get a connection......

show etherchannel 4 sum
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2

M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated

The database and XFS are not certified together. It should work, but if you ever have a problem you are on your own. Oracle's database support group can say "not our problem, because we don't support XFS" and Oracle's Linux support group can say "not our problem, because we don't support the database".

Does this matter? Probably not, as you are using VMware, which is not certified no matter what file system you use. The aphorism "might as well be hung for a sheep as a lamb" springs to mind.

Hi Alex,

i guess all your questions are answered in MOS ID #1632127.1. We also discussed this on Twitter some time ago.

> Anybody using xfs for Oracle 12c databases? Any experience with support problems due to this stack?

Yes, several of my clients are running 11g and 12c on XFS (OEL 6 and 7). No experience with support, because they had no issue until yet - just better I/O performance (in contrast to EXT)

Quoting Support Note 1304727.1

  • XFS - XFS is supported when using OL7 or RHEL 7. Oracle has not tested XFS with earlier versions of OL or RHEL.

FYI - Oracle Support's response to my SR: "As per the certification team, XFS with OL7 is supported for database."

This fact is also "kind of" expressed in the note pointed to by earlier in the thread: https://support.oracle.com/rs?type=doc&id=1304727.1

I am not sure why it has to be such a pain to get a clear, unambiguous answer to a question like this.

Thanks.
