I am going to build a couple of T5240's with LDOM 1.2 s/w in an as redundant
config as possible.
I Have two Emulex LP11000s cards with Sun Microcode and an additional
QuadGIG eth card in the systems.
I have Split the PCI bus and created the secondary I/O domain.
I have given the Scondary I/O domain a SAN card and the additional quad gig
card.
I have connected both FC cards to the SAN and both set of quad Gig cards to
the Cisco backbone.
I have tried booting the secondary I/O Domain directly from the SAN using
its local FC card.
THis doesnt work and I belive the Documentation also says that its not
supported.
I Can boot the secondary I/O domain off the primary domains FC card via
its VDS switch of course.
I plan to set up Virtual disk Multipathing using the mpgroup feature of
the VDS.
Now to the question:
IF I boot the Secondary I/O domain of the Control domains FC-Card and at
some later
point in time the Control domains SAN connection fails !
Will that crash the secondary domain as its boot disk will disappear ?
WIll this as an additional effect break the secondary I/O domains VDS to
the Guest
domains , so that the guest domains will loose both the disk paths
configured
in the vds mpgroup ?
Would it be a better solution to boot the secondary I/O domain from the
same
T5240 Local SAS disks as the the primary domain uses ?
