Starting Promise RAIDs with J-class expansion racks attached
It is very important when starting an Xsan using Promise Raids with J-class expansion racks to start the J-class units manually first and then to leave them to fully boot up for about 3 minutes before starting their attached E-class units.
The controllers in the E-class units need to have the J-class units fully operational during their power up in order to see the additional disks.
If you don't start them up in this order you might find that some of the disks appear to be off-line.
