Hi all,
Machines are 2x280R running Solaris 8 with full patches and a 3310 array with
dual controllers. 3310 is configured as a single bus. Also have 5x36G disks.
We have created 2 Luns on the array. One of them consists of 4 disks and it's
Raid 5 configuration and another one is created as single disk(noraid).
We tried to connect two 280R host to this array. And we want two hosts to be
able to access LUN's for Cluster Configuration(Active Active Cluster).
But we haven't done it with full success. We followed below steps.
1. First we created LUN (View,edit and edit Logical drives menu)
LUN0 -> Raid 5, 4x36GB disk
LUN1 -> Nraid,36GB disk
2. Changed Scsi Channels for host and assign
CH1 Host 0 , ID 0 (primary Controller)
CH1 Host 0, ID 1 ( Secondary Controller)
CH3 Host 1 , ID 0 (primary Controller)
CH3 Host 1, ID 1 ( Secondary Controller)
3. Map the CH1 ID 0 two LUN's
LUN 0 ID 0 (Raid5)
LUN 1 ID 1 (Nraid)
4. Map the CH3 ID 0 two LUN's
LUN 0 ID 0 (Raid5)
LUN 1 ID 1 (Nraid)
And then we tried to access LUN's from hosts. But we have only accessed one
LUN from each host.
When we moved LUN1 to Sec. Controller, we have accessed both LUNs from each
host.
But if we add more LUNs, we never accessed these extra LUNS.
Any ideas, comments?
Regards,
Devrim
