I did a bunch of asking around, combined all the answers, and then paraphrased: The IDs are assigned during the 1st power up, starting with the lowest available ID. If I add cards via HOT plug, I can pick and choose IDs. It depends on the exact hw that was plugged and in what order. FC 898 is 2 cryptos per card vs FC899 1 crypto per card Eric Rossman, CISSP® ICSF Cryptographic Security Development z/OS Enabling Technologies [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
