If you add an LPAR, you typically increase the number of devices by 100%, and if you add 2 LPAR’s, then by 200% and so on. So, if you have 64 devices defined on your FCP channel, 1 LPAR is 64 devices, 20 LPAR’s is 1280 devices.
In this instance, your limit is 480 devices, as per the CBDA291I message. Scratching my head a little, I think 480 is the maximum number of devices/sub-channels/QDIO queue pairs for a single FCP channel on a z10 Mainframe, but as you have specified what you configuration is (E.g. Server Type, FCP SCSI device mapping, number of LPARs. Number of channels, et al), it’s difficult to comment further. http://www-01.ibm.com/support/docview.wss?uid=isg2bb83cb638fd821d985257481006549d9&aid=1 Basically you can only define devices/sub-channels/QDIO queue pairs devices to an FCP channel and the message says you’re trying to define 1200… <Message Snip> Subject: FCP CHIP id From: Jake anderson <[email protected]> I was in process of modifying my current IODF and did below changes. 1) Added few more Chip id's including type of FC, OSD 2) added few more partition. 3) All these CHIP id, where I am getting below issue belong to FCP type now when I am trying to active this new changes, I am getting below error. / Sev Msg. ID Message Text _ E CBDA291I Maximum number of 480 device(s) on channel path 0.50 of # processor Z10A exceeded.
