Boot from FC SAN problem
Hi,
I have HP blade serwers with Adaptec SAN attached to it. Linux on servers. The problem with booting from SAN is when one blade server booted from SAN is working and second is booting, first is loosing connection to it's storage. It looks like booting the other server breaks frist server connection to SAN. I did another test and booted a non-blade server from hdd and mounted SAN storge, then I booted blade server from SAN. It was enough to reboot the hdd booted server to brake SAN connection to blade server. Anybode seen something like this? Any hints? tia mazek -- http://www.actus.org.pl/ - :::: - nic-hdl: MM3380-RIPE GnuPG 6687 E661 98B0 AEE6 DA8B 7F48 AEE4 776F 5688 DC89 http://www.poznan.linux.org.pl/ : http://www.netsync.pl/ |

Boot from FC SAN problem
You need to ensure that you are booting from different luns
Another couple of questions - how has zoning been implemented How is lun masking being achieved in you're configuration? thks Stuart.

Any hints? mazek, When you run into this problem, are both servers trying to boot from the same LUN on the SAN? I think that you need one LUN for each server to boot off of. Jim |

Hello,
I think, that it will be problem with the same LUN or bad zonning. Check this two thinks. Regards, Blazej napisał(a): Hi, I have HP blade serwers with Adaptec SAN attached to it. Linux on servers.
