Now that you have defined a basic cluster, you will want to add more nodes to it. Start by listing out all the unattached nodes. The next task is to add one of these nodes to your cluster, and you identify it by either its WWN or panelname, which is straightforward, except that they are called id and node-cover-name in the lsnodecandidate listing.
The detectmdisk command will rescan the system if you don't see LUNs on the system that you expect to be there. The -delim parameter separates the fields in the command output with a rather than a lot of spaces, so the output will hopefully not span lines. If you wanted to see all the managed disks then the command to use is lsmdisk.
You can add more mdisks by separating them with commas in the command above or you can add them to an existing MDG with the command. Now you have your managed disks placed into a managed disk group and all the space split into MB extents.
Next you need to format those extents up into a virtual disk that you can present to a host. To do this, use the command. Exactly how you do that will depend on what the host types are, so I'm going to assume that you know how to do this.
This command will check that your host is visible and will list out both its WWPNs. Here I'm creating a host definition for server P and connecting it with one port.
The SVC software consists of custom code running on a Linux operating system. The software performs target mode emulation for the attached servers and maps the logical unit numbers LUNs in blocks to the physical LUNs.
Functions like point-in-time copy FlashCopy , remote replication Global Mirror and Metro Mirror , and active-active stretched clusters HyperSwap represent additional advanced features that are optionally available. The virtualization of external storage systems from a variety of vendors is the primary function. The IBM SVC includes data reduction with compaction, deduplication, and compression of primary data, now included without an additional license charge. Data is deduplicated, compressed, and packed into allocation blocks as it is received in the SVC controllers and stored in a compressed form on the external systems.
