Oracle vm server 2.1.2 multipath problem

Question

hello
I had following error in my multipath configuration device-mapper: ioctl: error adding target to table i use hp eva 5000 Qlogic fc and hp blade
multipath -d lists all table but multipath -v2 -ll generates this error any ideas??
thx

Answer 1

even i am seeing the same issue on DELL EQLOGIC,
this error i am getting it whenever i start multipath
devices {
device {
vendor "EQLOGIC"
product "100E-00"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
my multipath -d o/p shows different uuid of disk and multipath -ll o/p shows diff uuid of disk - is this ok?
/var/log/messages shows
device-mapper: table: 253:0: multipath: error getting device
device-mapper: ioctl: error adding target to table
also could see soft lockup.
