I have done exactly so but I don't have any performance problems. Things you should consider might include:
- LPAR Weight compared to other LPARs you might have defined. - RAM for that LPAR. I have 8 GB. 512 might become a bottleneck (not necessarily but still...) - Do you have any other things running in your LPAR ? if so the relative share might be another aspect to consider. - I have 36 DASD (3339 cyl. that is, 3390-3 model) and the performance is fairly good. My system is a 2086-230 zSeries at 366 Mips. regards, José R. Barón e-mail: [EMAIL PROTECTED] -----Mensaje original----- De: Linux on 390 Port [mailto:[EMAIL PROTECTED] En nombre de Scully, William P Enviado el: martes, 16 de agosto de 2005 18:13 Para: LINUX-390@VM.MARIST.EDU Asunto: SLES 9 in an LPAR I'm having a performance problem. I was asked to install SLES 9 64-bit into an LPAR. To create the server I got my hands on the needed DASD and conducted the install of Linux under z/VM. The virtual hardware configuration (DASD and OSA addresses) were specified as would be used on the LPAR. As usual, the installation went well. The resulting copy of Linux can be booted under z/VM in perhaps a minute or two. However when I attempt to start this copy of Linux in an LPAR (512M and one dedicated CPU in an IFL on a 2094-313), it runs so slow you might think the software was written by folks in Redmond, Washington. It takes perhaps 15-20 minutes to boot. At times it seems to be completely unresponsive, even to the directly-connected HMC "Operating System Message" panel. I've encoded the so-called kernel timer patch both enabled and disabled, to no avail. And limited the DASD the kernel is to use with a DASD=nnnn-nnnn phrase in zipl.conf. But clearly I've missed something pretty obvious.
