ESS Specialist does not list the WWPN

Each Fibre Channel adapter on the nodes has a unique World Wide Number (Identified in ESS Specialist as World Wide Port Number - WWPN).


When creating a new host with ESS Specialist, select the appropriate WWPN in a scroll list. If you don't see this WWPN, ensure the following:

The link is correct. You should see the red laser light emitted by the host adapter on the fiber connected to the Storage Area Network - SAN (FC switch).

The FC adapters on the nodes and the ESS have the proper link type value of point-to-point or arbitrated loop. If you are unsure about your network topology, leave the default, which is arbitrated loop.

The command cfgmgr -vsl fcs0 has been run on the nodes.

Typical Oracle RAC configurations

All configurations are based on the following building blocks: Hardware Server nodes Storage Networking Software Operating system Cluster software Oracle RAC (application) Application architecture Oracle9i RAC on RAW devices is based on a shared disk architecture. Figure 2-1 shows a two-node cluster. The lower solid line is the primary Oracle interconnect, the middle dashed line is the secondary Oracle interconnect. For high availability, both these networks should be defined in the HACMP as "private". HACMP/ESCRM provides Oracle9i RAC with the infrastructure for concurrent access to disks. Although HACMP provides concurrent access and a disk locking mechanism, this mechanism is not used. Oracle, instead, provides its own locking mechanism for concurrent data access, integrity, and consistency. Volume groups are varied on all the nodes, thus ensuring short failover time. This type of concurrent access can only be provided for RAW ...

IBM SAN Multipath installation on Red Hat Enterprise Linux 5.X

This section describes the steps for installing Red Hat Enterprise Linux 5.2 on a multipath device. 1.Determine which multipath device your machine boots from. To do this, note down the LUN (Logical Unit) number of the bootable device that is made available by your Fibre Channel Adapter card during firmware boot. In the test environment, the firmware displays the boot disk, showing lun number 0.                           2.Start the installation by providing the keyword mpath in the kernel command line. In the test environment, linux mpath vnc was used. The Partitioning screen displays a list of multipath devices as mapper/mpath*. 3. Determine the multipath device that corresponds to the bootable device for the host being installed. Go back to the console window if using VNC, or start an alternate console. In the test environment, the System x® is hooked up to an RSA. In the remote control console,...

Configuring the virtual path devices

We recommend that you start with a "fresh" disk configuration, so it is a good idea to delete all previously configured FC adapters and their child (disk) devices. On node1, we checked which disks are still defined: {node1:root}/-> lspvhdisk0 0022be2ab1cd11ac rootvg activehdisk1 0022be2a3d02ead0 Nonehdisk2 0022be2a4cbbafd8 Nonehdisk3 none NoneThese are the internal SCSI disk drives {node1:root}/-> lscfg grep disk+ hdisk3 U1.9-P2/Z2-A8 16 Bit LVD SCSI Disk Drive (36400 MB)+ hdisk2 U1.9-P2/Z1-A8 16 Bit LVD SCSI Disk Drive (36400 MB)+ hdisk1 U1.9-P1/Z2-A8 16 Bit LVD SCSI Disk Drive (36400 MB)+ hdisk0 U1.9-P1/Z1-A8 16 Bit LVD SCSI Disk Drive (36400 MB)In order to include the ESS disks, run the configuration manager on each node: {node1:root}/-> cfgmgr -vSince ESS was configured with two host paths for each node (node1a and node1b), this results in two hdisks on the nodes. Actually, those two logical hdisks represent the same physical disk, accessed via the two ...
