There are three types of failover. 1.

A reboot reconfigure and the system was back up again. All Rights Reserved. Another thing we had to do was add mpxio-disable="no"; to /kernel/drv/fp.conf By Pascal Gienger on October 25, 2008 3:34 PM Yes, you're right, mpxio-disable="no" is needed in fp.conf. Alternately, to continue booting at your own risk, you may clear the service by running: "svcadm clear system/boot-archive" Aug 9 11:36:35 svc.startd: svc:/system/boot-archive:default: Method "/lib/svc/method/boot-archive" failed with exit status 95.
It's just like it doesn't attempt to perform the multipathing?? I have just inherited a pair of uspv's for second line storage. Join & Ask a Question Need Help in Real-Time? I'll check there.

The latter do arise when you want to use other devices (non-Sun), which is not really an uncommon practice...You have to tell scsi_vhci to ACCEPT your device based on the vendor- We use mpio with Windows servers and have for a long time just fine, even back in 3020 days...

It is used to set the logical-block size for symmetric multipathing in my example. During boot or when new LUNs are presented to the Solaris host, the configuration pages of the LUN are automatically read to determine the LUNs capabilities and Identity.

They are part of the game. The optimized paths are the ones with a direct path to the storage processor that owns the LUN.
