Linux continues to become a mainstream solution, often at the expense of Unix. Many of the implementations of Linux have come in organizations that are classic Unix shops. The success of Linux in these organizations has come from both replacing some or all of the existing Unix servers, and equally importantly, capturing growth opportunities for installed systems.  Migrations of applications that were once running on a Unix platform are happening more frequently as organizations look to reduce costs.

While a move to Linux helps reduce server and software costs, other challenges are introduced into this environment. Linux’s native operating system tools are not ready to handle many mission critical tasks.  In order to perform many complex storage management and high availability tasks, applications must be taken down.  Migrations to Linux from Unix are difficult as well and may require long periods of down time.

Recently we got an escalation from the field on AIX in which we saw that gab paniced the node because it got a packet with a wrong sequence number. On further debugging we found that everything was correct except that 1 bit in the gab sequence number was flipped from 0 to 1 thus causing gab to panic the node since it suspected data corruption.
 
So, we asked the customer to enable LLT checksums (which are disabled by default) and see what happens. With LLT checksums enabled we saw that one of the LLT links reported a few LLT checksums errors and then again gab paniced the node with the same error - same sequence number bit flipped from a 0 to a 1.
 
So, we then asked the customer to turn on LLT checksum level 2. This level basically calculates 2 checksums, one for the messages received from gab (called mcksum - which is verified for corruption just before we deliver the msg to gab on the receiver) and one for the full...

A few weeks back a large number of Product Managers, Technical Product Managers, and Sales Engineers (SEs) gathered for our annual SE Symposium in Las Vegas.  VCS One was definitely on everyone's mind, especially with the upcoming 5.0 release.  Here's a summary of the Q & A from the VCS One sessions I attended.

Question:   How many Policy Masters (PMs) are needed for a VCS One Cluster?
Answer:      One PM per cluster.  Larger environments will implement multiple VCS One Clusters per data center.

Question:  Does the PM have to run in an active/passive cluster?
Answer:     Do to the critical role of the PM dedicating hardware is best to ensure performance, reliability, and availability.   

Question:  Can we run other apps on the PM cluster?
Answer:  ...

If you want to reduce extra traffic on the LLT links one small thing to do would be to add the following line to /etc/llttab on all the nodes in your cluster (say 2 node cluster):
exclude 2-31

What the above line does is that it assumes that your cluster will always have only 2 nodes (0 and 1) and hence extra packets will not be sent to discover the other nodes periodically. One caveat is that you won't be able to add a node to your cluster on the fly. You could also change the above line to be:
exclude 8-31
and in that case you can grow your 2 node cluster to a maximum of 8 nodes on the fly.

One more thing to note when using LLT is to never have spanning-tree enabled on the switch ports which are used to connect the LLT links. Spanning tree causes a delay in sending pkts when the port is enabled and this can cause the cluster nodes to not join properly.
