This Presentation is an overview and customer example on how to leverage Storage Foundation HA/DR for Oracle when using Solaris Zones.  Architecture detail, cluster examples and best practices are highlighted throughout the document.  This was developed as a co-presentation for the 2007 Symantec Vision conference.

This presentation was given at Collaborate2009 and covers how to create virtualized Oracle servers utilizing Solaris Zones and make them completely portable, even to another data center.

The solution is accomplished with the Solaris OS, Oracle RDBMS, and Symantec (Veritas) Storage Foundation HA/DR. The portable “Oracle zones” are storage and replication-method agnostic, and the database files are “wrapped” so they can even be transported to other *nix platforms for backup or migration purposes.

It seems that some customers want to create a trunk out of two links and then create vlans over that trunk and then run LLT over those two vlans.

This is how to do this on Solaris:

Create a trunk (aggregation first) out of the two bge links:
dladm create-aggr -d bge2 -d bge3 1 <--- to create a aggr1

Create vlans out of aggr1:
dladm create-vlan doesn't seem to work on Solaris 10u7 (beta).
So just do the following:
ifconfig aggr10001 plumb 1.1.1.1 up <----- to create /dev/aggr10001 (vlan id 10000)
ifconfig aggr20001 plumb 2.1.1.1 up <----- to create /dev/aggr20001 (vlan id 20000)

Then create /etc/llttab as follows:
link link1 /dev/aggr:10001 - ether - -
link link1 /dev/aggr:20001 - ether - -

And now you are up and running with LLT over vlanned trunks.

If you have LLT working over the ce driver on Solaris, one small change that you can make to help performance problems in your cluster would be the following:

The /etc/system file on all hosts should have:
set ce:ce_no_tx_lb=1
set ce:ce_taskq_disable=1
set ce:ce_reclaim_pending=1

A reboot is required.

A group of DBAs that manage large databases at a large federal government agency had the challenge of migrating a mission-critical 35 TB database from a Fujitsu 2500 running Solaris to an IBM P595 running AIX within a 4 hour maintenance window. Using the tools that the database vendor offered, the estimated time to move that much data was in the neighborhood of 3 weeks, which was unacceptable. Database migration tools from another company were evaluated but they were cost prohibitive.

A Symantec Sales Engineer suggested that these DBAs use the Portable Data Container (PDC) feature within Storage Foundation, which was already deployed in their infrastructure. He explained that with PDC, instead of moving the data from one storage location to another, the data can be unmounted from the Solaris system and mounted on the AIX system. The entire process would take no more than 30 minutes.

The PDC feature was tested in the customer’s lab environment and was put in...

This document is not listed on the IBM web site so i have attached it here (hope the mods will let it stay)

It details the LTO drive status codes and there true meaning. We all have seen the Media errors from Netbackup, backupexec, and so forth. This document details what you see from the web gui of a 3500 series tape library or maybe you have another gui accessing this information. Either way i hope you get some good use out of it. I know i have.

The first basic function for a multi path (MP) driver is to identify the set of block devices that can be supported. The device discovery is generally triggered when the MP driver is loaded into the operating system (OS) as part of boot process. During early boot, not all devices connected to the system may be available. For example, the devices connected using the fibre channel (FC) cables may not be available during early boot time unless there is special support from the bootstrap, which is usually from NVRAM or EEPROM, to identify the fibre channel devices. In any case, it may be required for a MP driver to rescan the OS device tree at a later stage of boot process.

One of the biggest challenges in device discovery is the ability and skill of MP driver to discover disk devices and their attributes in a non-intrusive fashion such that the disk media is not touched. In other words, the device discovery has to be purely read-only operations to identify the disk and disk...
