The idea is to make a smooth transition from harc v4.0.30 to v4.1.22 by putting in my cold-spare harc card in the chassis and upgrading that. Then I can move dsps to it one at a time such that we're never down and nobody gets arbitrarialy disconnected. Before I stuck another harc in the chassis, tho, I figured I'd better make sure that the dsps were owned by the existing harc so the new one wouldn't try to grab 'em. So I go into my semi-trusty HARM (v1.0.8), pick "Tables->Chassis Configuration", and for each card, I select it, hit 'Edit', click the 'owner' checkbox, and hit 'Ok'. Then click 'Set' to configure the changes. And immediately knock off all current connections, and begin refusing calls with a fast busy. I quickly go back in and put things back, and everything returns to normal. So I guess my question is, "huh?". I guess I have another question too, one which I should pose before I do anything anyway. First, my relevant version numbers: s/w h/w HDSP: 1.2.5 0.49.0 HARC: 4.0.30 1.0.0 NMC: 5.5.5 6.0 TCMW: 5.5.1 HARM: 1.0.8 I want to give hdsp v2.0.51 a shot as well as the aforementioned upgrade of the harc to 4.1.22. I have a couple of concerns about this, however. First off, my versions of nmc, tcmw, and harm are not listed in the compatability lists in the release notes for the new harc/hdsp software releases. And of course, those upgrades are unavailable to me since I let my service contract expire last year. So, I'm stuck with those. I can either use my system as it was represented to me when I bought it and live with security problems on the harc (and relatively broken code on the hdsps)....or I can upgrade to these current software versions and lose the functionality of a nmc and windows-based management. Or maybe it's not all that bad? And is there an issue with the new hdsp version on v0.49.0 dsp hardware? What's the summary on that one? - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
