Add minidisk to active Linux instance

2005-04-08 Thread Kinnear, Mike
Sorry, my mistake. The volume I was trying to link had not been attached to the system. Surprisingly, it worked a lot better after I attached the device. -- For LINUX-390 subscribe / signoff / archive access instructions, send

Add minidisk to active Linux instance

2005-04-07 Thread Kinnear, Mike
How can I add a new minidisk to an active Linux instance without IPL'ing that instance? I've created a full pack minidisk (minus cyl 0) and formatted it. I've added the MDISK statement to that user's directory entry. I've issued the DIRECTXA. I can't get a '#cp link' or '#cp att' command to

LVM - maximum PV's?

2005-03-16 Thread Kinnear, Mike
On a SUSE SLES8 system I've created an LVM with 15 full mod-3 3390's and 8 mod-9's. I cannot get the 9th mod-9 to becoem a member of LVM. the pvcreate appears to work OK, but the volume is not on the pvscan list, nor included in the vgdisplay total. Any ideas?

VSWITCH and HIPERSOCKETS

2005-01-19 Thread Kinnear, Mike
I've researched the archives and redbooks. I think I've come across every combination of implementation except the one I'm trying to do. We have a number of VSWITCH LINUX instances running under one z/VM LPAR. We have a production VM TCP/IP stack that we use for 'older' VCTC connections until

Real/virtual memory ratio

2004-03-08 Thread Kinnear, Mike
We use z/VM for a Linux environment. A Redbook, http://www.redbooks.ibm.com/redpapers/pdfs/redp3661.pdf http://www.redbooks.ibm.com/redpapers/pdfs/redp3661.pdf on page 7 says you should have a 1.5/1 virtual to real ratio for Linux environments running Websphere applications. We've been running

Memory displays on Linux

2003-07-29 Thread Kinnear, Mike
We recently encountered an application loop with a Linux Websphere instance. I was able to get a VM PER Branch trace, but I cannot find any command within Linux to display those memory locations or to determine where modules are actually loaded. The code does not have any 'eyecatchers' either, so

ESALPS vs. VMRTM/VMPRF

2003-06-12 Thread Kinnear, Mike
Has anyone running Linux under VM attempted to compare or evaluate the differences between the Velocity Software's ESALPS and IBM's VMRTM/VMPRF? What were your conclusions as far as function and value? Thank you for your help.

Communication between Linux and z/VM

2002-02-27 Thread Kinnear, Mike
I am trying to develop an exec that will shut down a Linux instance from VM user MAINT. I have figured out how to become a secondary user and log on as root and provide a password using CPSEND mechanism. The problem I'm having is being able to code a routine that can parse a response sent from
