You right. NPIV. I am wondering , if it is an issue to not use it when booting off a san.
I am from a linux san world where only cluster disks would be on the same scsi bus. (using a cluster container) I am not 100% sure , but it seems when the system is starting, it runsinitrd and the modules for the devices load our system might find other disks on the bus. It could be something unrelated but our san disks don't seem to work well (stable) for holding root and swap. When booting I get a message that it can't mount the rootfs. I don't see any other disks on the scsi bus when I boot the system from a non-san drive. I seemed to remember a similar rootfs bug related to sub_fs and lvm, so I realize it could be a lot of different issues, but I am wondering it has ever been found that the wfcp driver will probe the scsi bus at bootup if another scsi or dm module loads. 2010/8/23 Rogério Soares <[email protected]>: > i think he want say NPIV.... > > On Mon, Aug 23, 2010 at 8:42 PM, Mark Post <[email protected]> wrote: > >> >>> On 8/2.3/2010 at 07:00 PM, martin roby <[email protected]> wrote: >> > Has anyone ever run zlinux , booting of san disks without nvio? >> >> What is NVIO? >> >> >> Mark Post >> >> ---------------------------------------------------------------------- >> For LINUX-390 subscribe / signoff / archive access instructions, >> send email to [email protected] with the message: INFO LINUX-390 or >> visit >> http://www.marist.edu/htbin/wlvindex?LINUX-390 >> ---------------------------------------------------------------------- >> For more information on Linux on System z, visit >> http://wiki.linuxvm.org/ >> > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO LINUX-390 or visit > http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- > For more information on Linux on System z, visit > http://wiki.linuxvm.org/ > ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
