I can vouch for that . I have been working with HP for
more than 5 years and I find it very reliable and
efficient OS .

Not necessarily . You can use it for single instance
more easily . MCSG is just a set of shell scripts
allowing you to escape from hardware failure of
MACHINES...not the storage unit . The conf. is 2
machines configured to recognize same mount points
from the storage unit . So setup should be done
carefully like the ORACLE user id and Group id's
should be same on both machines .

CAREFULL...!! This depends . Decision of using
AUTORAID should be taken after carefull thought . The
AR is a "BlackBox" ...literally . HP refuses to
divulge any info on that . But this much is known from
experience : AR starts off with RAID1 and as you put
more data into it at one point when AR decides to go
for RAID5 , all the applications will run into
stonewall because AR is busy converting itself into
RAID5 and will not process any IO requests..!!!
