Simple OSA-Express question.....
For redundancy's sake, we are purchasing another OSA-Express card soon. The issue is that we only have one free ESCON channel available and the OSA card requires two (one for each port). The manuals seem to assume that you're going to define the pair at the same time. My question is, can I just define one port and leave the other port undefined until such time as another channel frees up? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

However, I don't understand what does it mean 'ESCON channel available'. Do you mean free ESCON port or free CHPID ? ESCON port is totally unrelated. You can have free ports, or no. Free chpid number means, you have many channels: close to 256 CHPIDs. In that case it is related to new OSA. -- Radoslaw Skorupka Lodz, Poland -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Simple OSA-Express question.....
Hi, Arturo is correct that you can define one or both of the OSA ports that you will get with the new OSA card. You will need to find out what PCHIDs will be assigned to those ports so that you can correctly define them with the CHPIDs. You should be able to get the PCHID numbers from your SSR or sales rep. Also, do you mean that you have one ESCON channel (CHPID) remaining or did you mean that there is one slot remaining which is where the new OSA card will be placed? ESCON and OSA are two separate channel types and they come on separate cards. The OSA card has two ports (or CHPIDs) per card. The ESCON card has 16 ports per card (15 are useable, 1 is a spare). -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Ok, I feel stupid now (ok, more so than I usually do). I momentarily got the channel ports confused with CHPID numbers. I'm not anywhere near the 256 CHPID limit so I've got plenty of those to choose from. Case closed and thank you gentlemen for jogging my memory. :o) -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
