Ordered more memory
The updates of PHP and WordPress seem to require more memory: the blog loads slower, and paging has increased. This was expected – but not in this amount. So I ordered more memory to fill the system to the max. It will take some time to get it, and installing it means the system won’t be available for some time. I take the opportunity to install a SCSI card as well so I can hook up the disks directly to the machine, and get rid of the HSZ50 unit: the battery is gone so caching is disabled and access is now limited to 5Mb/sec; since I have only one controller board, it is of no use for clustering: I tried but it simply doesn’t work with the Workstations: these crash dramatically. Or does someone have left-over controller board, cache and battery units?

New hardware running
I had to power off all systems for some time, because work needed to be done on the power grid at home – and given the structure of the system, it meant I had to shutdown the PWS and storage for some time.
It gave me the opprotunity to install the new DS10 in stead of the PWS.
While the systems were down, I installed one of the KZPBA-CY controllers I still had available, and removed the SCSI cable from the PWS – together with it’s disk. But where the workstation has a built-in SCSI controller, the DS10 lacks such a device. But I had a KZPBA-CX somewhere so that was installed instead.
The system booted from the local disk so it looked fine.
Next, I connected the system to the shared SCSI bus, like the workstation was connected. But no disks showed up!
Next I booted, again, from the local disk and foud that the KZPBA-CY that connects to the HSZ50 of shared SCSI had 360 errors: teh device was bad! That explains teh problems I had with this device as well.
The card was swapped with the one from the workstation, which has proven to work fine. And that helped – the new incarnation of Diana now runs fine – as long as the system doen’t get overheated: the older hardware is less sensitive, I think. Well, we’ll see.
And what’s fine: the new machine holds a far more sophisticated video card: ATI RADEON 7500, allowing me to write this from the console 😉
I just have to create a new home-page file…
