Remove DASD device

2017-05-30 Thread Jorge Fábregas
Hi, We have a situation with two SLES11 servers. We had to migrate the underlying PVs used for the swap logical volume (we used pvmove to move from DASD to FCP LUNs) and then we removed the DASD PVs from the volume group (followed by pvremove on them to wipe LVM metadata). After that I called

Oracle DB Certification on SLES12

Hi everyone, Does anyone here knows if we will ever see Oracle certify its DB against SLES 12 on s390x? It has been a while since they certified it against x86. If I ask IBM about it they (appropriately) tell me to ask Oracle. If I ask Oracle they tell me to open a support case. If I open a

SLES 11 SP4 - Kernel locking up

Hi everyone, We're having some kernel locking issues after installing the latest kernel for SLES 11 SP4 (kernel-default-3.0.101-77.1). This is on two separate Linux guests and it happens - right away- after starting some network applications: Linux completely freezes. If we go back to the

Hi, We have an issue with new deployed systems from our SLES 11 SP4 template (They all have "zfcp.allow_lun_scan=1" on their zipl.conf file). Whenever the z/VM admin deploys a new image, he would assign two FCP devices. After that we take control of the system and: 1) verify FCP devices are

Hi, I need to use the watchdog provided by z/VM (with the vmwatchdog kernel module) but I've just found out its "timeout value" isn't configurable. There's no module parameter for that. It's hardcoded at 1 minute (I had plans to change it to 5 seconds or 10 seconds). If I can't change it via
