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..!!!
