StorEdge 3510 FC array Configuration

Hello,

I'm running Solaris 8 on a Neta 20. I have 3 StorEdge 3510 FC arrays attached; one controller each array. Each has 12x146 drives for a total of 2TB each array. As this if my first time dealing with this array, I need some advise. I configured my first array with one logical drive and 4 partitions. maped the luns, and reset. (oh I changed the seq to ramdom)

I am now trying to configure the 2nd array, however it will only let me make a logical drive of 512GB max. I've tried everything I could think of to overcome this. Any ideas, I was talking to someone today and they mentioned that solaris will only reconize 1TB. Is this true? If so does anyone have any ideas on a better way to configure the arrays. They will be used for large oracle databases.

Thanks

I presume that by now you have sorted this problem, but in case not, 512Gb is the maximum logical drive size when the i/o optimisation is random.

On the max disk size, I read somewhere that VxFS might help.

I found your query when looking for help on directing StorEdge events to the syslogd on our central loghost - which I still haven't found out how to do!?

Random optimization should not be used with high-capacity configurations. Use sequential optimization instead. Random cache optimization greatly reduces the maximum number of supported disks.

I ever read in the 3510 book. I/O random is usefull for database, while sequential is for video streaming.Max lun size for random is 512GB while sequential is 2TB

The 1TB limit is down to Solaris8. You need 2.9u4, which supports 16TB.HTHJohn

The array has it's limits and Solaris has its. Don't confuse the two. :)
