2. switch settings at the front of BCCs: split bus (0 position) and SAF-TE (1 position). This way there will be two independent busses dedicated for each BCC. In this mode left BCC will drive disks in slots 8-14, and right will drive 1-7. After connecting BCCs to different SCSI adapters use MirrorDisk/UX to configure logical volume mirroring

Re: ** Configuring JBOD 2300 **
I kind of understand your response. It looks like one BCC is contolling 7 disks and the other is controlling 5. Do I need to make this 6 and 6 and is that possible? Is it really necessary for an effective mirror?

Re: ** Configuring JBOD 2300 **
The workflow should be:
- 'balance' disks across busses (see Vince's reply);
- pvcreate all needed disks;
- include all needed disks into one volume group (vgcreate);
- create original logical volumes (lvcreate) pointing LVM where to create them (indicate path to physical volume within VG to create LV on), use only one set of disks (seen by one HBA);
- create mirror copies (lvextend -m) on disks seen by another HBA.
Note: better plan where volumes will be created first, draw diagram, and then create. This diagram will help you not to make a mistake and will serve as a reference in the future
