For the zEC12, each FCP channel (CHPID) can support up to 480 subchannels, where each subchannel represents a communication path between software and the FCP channel. Each FCP channel can support up to 480 QDIO queue pairs. This allows each FCP channel to be shared among 480 operating system instances.
http://www-01.ibm.com/support/docview.wss?uid=isg2a7ff43cc0a86a31a85257a620052a0a7&aid=1 OK, so you had 4 LPAR’s with 120 devices, and you’re trying to add 6 LPAR’s, with the same 120 devices, hence the increase from 480 to 1200 (E.g. 4 LPARs * 120 Devices = 480 & 10 * 120 = 1200). If you need 10 LPAR’s, then the maximum number of devices per FCP would be 48. If you need 120 devices per FCP, you will have to consider increasing the number of FCP (channels) you’re using. Then you would have to divide 1200 (10 LPARs @ 120 Devices) by 480 (Maximum Number of Devices Supported), which would be 3, rounded up. Subject: Re: FCP CHIP id From: Jake anderson <justmainfra...@gmail.com> <Message Snip> We are actually migrating z10(2097-E26) to zEC12( 2827-H43) Mainframe. So, I have updated the Machine type model as well in HCD along with new LPAR defination. Initial I had 4 LPAR but I have added 6 more new LPAR. Also below are my defination of FCP chip id . Can you please suggest what changes I should make to add these FCP chip id's in the access list of these new 6 LPAR's.
