If sled(s) or drive(s) are physically missing from 
the array, the entire stripe group (LUN) 
containing the drive(s) will be unavailable. To 
determine which drives would be unavailable in 
various configurations, see Exhibit 6.2-1 and 
Exhibit 6.2-2.
To remove RAID Level 0 groups
1
Connect to the array via the RS-232 port or the 
optional Ethernet management services card 
(refer to 
on page 17). You 
should now be in CLI. 
1
Continue with the CLI or access the RAID page 
of the ExpressNAV interface (refer to 
ATTO 
ExpressNAV: Browser-based Interface 
on page 25). 
2
Type set QuickRAID0 0 to configure the array 
in JBOD mode.
3
Continue with steps 4 through 7 of 
Exhibit 6.2-1  Sled-based QuickRAID0 stripe groups with LUN designations in a fully populated Array set up as 
QuickRAID0 6 sled. If sled 6 were to be withdrawn from the array, LUN 3 (grayed boxes) would be unavailable.
Exhibit 6.2-2  Drive-based QuickRAID0 stripe groups with LUN designations in a fully populated Array set up as 
QuickRAID0 6 Drive. If sled 6 were to be withdrawn from the array, LUNs 2 and 5 would be unavailable.
