Hi,
This question is a follow-on to a posting I made a while back regarding
what turned out to be the rather unwise practice of mounting a HP XP512
SAN file system on two machines - one R/O and the other R/W.
It was pointed out to me that the standard UFS file system does not
support this kind of activity, and it was suggested I use a file system
which supports this type of shared access.
The environment is a Sun E450 (Solaris 7) and a SunFire V880 (Solaris
8), both of which are connected to an HP XP512 SAN via JNI Fibre HBA
cards. I want to be able to read and write from one host (The V880) to
the file system on the XP 512, and only read the same file system on the
E450. R/W on both hosts would be an obvious bonus :)
Which of the Veritas products are needed to make this work? Just VxFs?
Veritas cluster?
The other alternative is Suns QFS file system. Is SAM-QFS needed?
Any experiences with either of these file systems in this type of shared
environment?
Thanks
Scotty
