Samat, it's hard to imagine an IPL would *ever* be required in these circumstances. IPLs obviously restart all of z/OS (per LPAR), including z/OS networking, but that's terribly "brute force" and not required unless the operators are simply not sufficiently familiar with z/OS networking.
So I think that's what you check, whether your operators know what to do when moving cables from an old switch to a new switch. If they don't (or aren't sure), hiring an expert operator to help with the switchover and/or investing in some training -- and capturing much of that knowledge in automation -- would all be good ideas. If the switchover is well planned and well executed it's likely it would be nondisruptive to users. Best practices recommend at least dual pathing all networking associated with z/OS, and hopefully you're starting from that configuration. If you're not, then that gap can be addressed first. (And as a general rule "add" first, then, very carefully, "subtract.") -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA -------------------------------------------------------------------------------------------------------- E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
