Test 000-332: High Availability for AIX - Technical Support and Administration -v2
- Design a cluster with suitable hardware and to minimise SPOFs
- Evaluate cluster security requirements
- Determine interdependencies of cluster components including resource groups, parent/child relationships, locations, dynamic node priority, application priority, capacity on demand, etc.
- Determine other application requirements for cluster integration
- Plan cluster topology and AIX requirements, including IP and network configuration, IPAT, host file configuration, fibre channel adapters, storage components, MPIO / drivers, and NPIV.
- Plan a cluster within a virtualized environment
- Understand at a basic level Cluster Aware AIX (CAA) capabilities and requirements
- Understand differences between PowerHA 6 and PowerHA 7
- Identify required software elements including AIX levels, filesets, and HA Standard or Enterprise editions, including replication options
Installation and Configuration (22%)
- Perform PowerHA installation
- Configuring topology components (e.g. persistent IP addresses, IP and non -IP networks, nodes, IPAT via aliasing and replacement, site configuration, network modules, etc.)
- Understand HA in conjunction with Heartbeat over IP aliasing,Etherchannel, Multicast IP address.
- Implement LVM or GLVM between two separate sites (between systems, buildings or cities)
- Verify AIX prerequisites have been addressed
- Configuring netmon.cf file
- Implement cluster security including LDAP, RBAC and EFS security options in 7.1
- Define custom events (user defined events, and pre and post events)
- Configure resources (including service IP, resource groups, resource group dependencies, nfs, VGs, etc)
Perform Cluster Migrations (6%)
- Determine migration methods, including considering what level of HA is installed at the target of migration (not clusters all migrate to 7.1)
- Determine migration tasks and solve problems related to migrating from PowerHA 6 to PowerHA 7
Testing and Verification (5%)
- Testing cluster components and validate cluster configuration, including fallover, fallback, cluster start and stop, and simulated network failure).
- Using the cluster test tool
Daily Administration (35%)
- Manage resource group components, including nfs
- Analyze cluster status
- Verify and synchronize the cluster
- Administer resource groups, including application monitors
- Managing PowerHA file collections
- Using C-SPOC and understand what functions are available including managing cluster users, passwords, shared VG and filesystems
- Backing up and restoring the cluster
- Configure error notifications
- Add or remove components during cluster operation
- Create application monitor
- Understand cluster events and their impact on the cluster
- Using DLPAR within a resource group
Problem Determination and Resolution (11%)
- Recover from failed events and from failed DARE operations
- Recover from script failures and config_too_longs, etc.
- Analyze and manage critical logs, including understanding cluster events and processing order
- Configuring cluster tunables
- Understand how RSCT detects failures
