#271519: Solaris 10 Kernel Patches 141444-09 and 141445-09 May Cause Interface Failure in IP Multipathing (IPMP)

Category : Availability
Release Phase : Resolved
Bug Id : 6888928
Product : Solaris 10 Operating System
Date of Workaround Release : 03-Nov-2009
Date of Resolved Release : 10-Dec-2009

Solaris 10 Kernel Patches 141444-09 and 141445-09 cause interface failure in IP Multipathing:



1. Impact

The IP Multipathing (IPMP) facility allows systems with multiple network interfaces in the same subnet to failover in the event that one of the interfaces fails, and then failback when the interface is ok.

Solaris 10 Kernel Patches 141444-09 (SPARC) and 141445-09 (x86) cause interface failure in IPMP when configured for probe based failure detection. This issue does not occur with a IPMP link based failure detection configuration.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform:

* Solaris 10 with patch 141444-09 and without patch 142900-02

x86 Platform:

* Solaris 10 with patch 141445-09 and without patch 142901-02

Note 1: Solaris 8 and 9 and OpenSolaris are not impacted by this issue.

Note 2: This issue only occurs on systems with IPMP configured for probe based failure detection. This issue does not occur with a IPMP link based failure detection configuration.

Description

please see evaluation in 6879232, essentially after adding 141444-09 to my cluster nodes, reboot hangs, as my cluster nodes has exhausted the default number of autopush structures.
When the clhbsndr module is loaded, it causes a lot more autopushes to occur than would otherwise happen on a non-clustered system.

So cluster needs to update /etc/system with
set nautopush=64

this has also been seen by one external customer so far, University of Queensland.

Enda

Work Around

edit /etc/system and add the line:

set nautopush=64

The man who sold hot dogs (Author unknown)

There was a man who lived by the side of the road and sold hot dogs.

He was hard of hearing so he had no radio.
He had trouble with his eyes so he read no newspapers.

But he sold good hot dogs.

He put up signs on the highway telling how good they were.
He stood on the side of the road and cried: "Buy a hot dog, Mister?"

And people bought.

He increased his meat and bun orders.
He bought a bigger stove to take care of his trade.
He finally got his son home from college to help him out.

But then something happened.

His son said, "Father, haven't you been listening to the radio?
Haven't you been reading the newspapers?
There's a big depression.
The European situation is terrible.
The domestic situation is worse.
"

Whereupon the father thought, "Well, my son's been to college, he reads the papers and he listens to the radio, and he ought to know."

So the father cut down on his meat and bun orders, took down his advertising signs, and no longer bothered to stand out on the highway to sell his hot dogs.

And his hot dog sales fell almost overnight.

"You're right, son," the father said to the boy.
"We certainly are in the middle of a great depression."
