Hello,
I'm trying to use the multipath software in my project. I downloaded and
installed the 2.6.12.rc2-odm1 (I turned on the Multi-Device
support/Device
Mapper Support and Multipath I/O Support)
I also download and install the mutipath-tools 0.4.4. But when I tried
[root at dhcp76 multipath-tools-0.4.4]# ./multipath/multipath
device mapper prerequisites not met
I don't known what's wrong with it. I ran dmsetup
[root at dhcp76 multipath-tools-0.4.4]# /sbin/dmsetup targets
striped v1.0.2
linear v1.0.1
error v1.0.1
Is that mean I don't have multipath support compiled in the kernel ?
Also, I have a generic question regarding to the multipath tool. We ran
some
virtualization softwares, which generate different UUID (SCSI VPD 83)
for the
same LUN go through different path, can the multipath software config
these
two LUNs with difference UUID in a multipath setup ?
Best regards
