Ian Ian, This is usually down to the tape rather than the drive. It is recommended that you 'bake' old tapes before reading them - over time they become 'sticky'. IIRC a couple of hours at around 50 degC. I have a load of tapes that I need to read off but I've currently got no way of baking. I suspect that a standard oven, even on it's lowest setting, will be too hot - you need something like an incubating oven. I know someone who used to do this on a regular occasion and had very few failures using this method. Regards, Mark. Is the takeup leader (the plastic ribbon which is fastened to the internal reel) intact? Its outer end which grabs the tape from the cassette is arrow-shaped. Is the "arrow" quite in order? If not, the takeup leader should be replaced. You can also read a TK50 tape with a newer DLT drive like TZ85, TZ86 and TZ87. As Mark said, the tapes tend to deteriorate even when stored in good conditions. It is recommended to retension the tapes at least once a year by winding it completely in and out. That recommendation is written in the tape manufacturers' preserving guide. It will also prevent edge deterioration. Regards, Kari

I started it to ask for opinions on rack mount intel servers to use as a base for mostly hecnet stuff. Sent from my iPhone On 24 Jan 2013, at 08:44, "John H.

New Node please, 4.245 ENGINE

by mark＠wickensonline.co.uk

Johnny, Could you please add node 4.245 ENGINE to Hecnet. This is a 're-purposed ZX6000' - I bought an RX2600 motherboard and have swapped it into the ZX6000 case. Regards, Mark.

The downside is that I have to run the VMWare vSphere Client on a Windows platform. In this case it's Windows 7 running on my Mac Pro inside a VMWare Fusion VM. You can do a lot of stuff from the BB shell within ESXi, though the command structure is somewhat obtuse. It's handy in emergencies. If you're just bringing up or shutting down VMs, etc, it's very easy to deal with, and you don't need to sully yourself with Winblows and end up with that "not so fresh" feeling. With the move to ESXi from "full blown" ESX VMware has been moving more and more out of the ESXi host. Are they reducing the functionality that's available there? I don't *want* full-blown ESX. I wish I could tell. The product descriptions on the website are a bit too full of buzzwords for me to figure out what's actually being said. The things you can do in BB are *very* limited. Nah. Here's my quick cheat sheet, which is only the stuff I've used: vim-cmd vmsvc/getallvms # lists VMs vim-cmd vmsvc/power.getstat <vmid> # get power state vim-cmd vmsvc/power.on <vmid> # power on VM vim-cmd vmsvc/power.off <vmid> # power off VM vim-cmd vmsvc/power.shutdown <vmid> # shutdown vim-cmd vmsvc/power.restart <vmid> # restart vim-cmd hostsvc/maintenance_mode_enter # enter maintenance mode vim-cmd hostsvc/maintenance_mode_exit # exit maintenance mode vim-cmd vmsvc/unregister <vmid> # remove VM from inv. vim-cmd solo/registervm /path/to/<filename>.vmx # add VM to inv. vim-cmd vmsvc/message <msg_num> # get messages So, basically anything except creating a new one or re-provisioning disks or other resources...and I've done THOSE from the BB shell as well, though not often enough that I've put it in my cheat-sheet. Useful cheat sheet. However, you can download the API tools (perl or PowerShell versions available) or install the VMA (Virtual Management Appliance, just a linux box with the tools already installed) you can do everything you need to do from the CLI of your favorite OS. Got a link for that? And will it work with 4.1? A quick google seems to only mention it for 5.0 :( If you can use vCenter, the web based GUI in 5.1 is FANTASTIC and only required flash. Works fine in Chrome. If you need keys for 5 I might *cough* know *cough* where *cough* to get some. *cough cough*. :) Hmm! Please to be sending! Can I do an in-place upgrade from 4.1 to 5? I could use a key I think .I'm not sure which product I want through due to the number of buzzwords on the website. -Dave -- Dave McGuire, AK4HZ New Kensington, PA -- Cory Smelosky http://gewt.net/ Personal stuff! http://gimme-sympathy.org/ My permanently-a-work-in-progress pet project.
