StorEdge 3320

As you see on the pics, 3000 family arrays come as array with controller or JBOD (no controller - as extension unit).
This doc is only for JBOD. Here are some tips and procedures from my hands on experience.
Power On sequence
1. The 3320 JBOD
2. The Host (in this case host can discover additional drives).
Power off sequence
1. The Host (this will stop I/O)
2. The 3320 JBOD
If there is need only for JBOD to be power off (not host), make sure to stop all I/O activates (like unmount JBOD drives).
Disk drive replacement
Disks are hot-swappable, can be replaced when the 3320 is powered on.
Since this is JBOD, you need physically to determine failed disk.
1. Record cable connection between host/jbod
2. Look for disk's amber LED
3. Use format and cfgadm -al to find disk logical name
4. Replace disk (take out for 1 inch and wait for 20 sec to stop spinning)
5. Place new disk
6. Use devfsadm (if disk is not recognized) to rescan disks.
7. If 6 doesn't help, create /reconfigure file and reboot or boot -r
Check information about loaded modules for SCSI drives.

Module configuration files are in /kernel/drv directory.
You may need to check them in order to enable more SCSI targets. Files of interest can be sd.conf, st.conf, ses.conf, etc.
Single/Split (or Dual)-Bus Configuration
Drive-bus configuration determines how drive ID is assigned to channels.
Usually channel 0/1 are for internal disks and cd/dvd-rom.
Disks from expansion unit (JBOD) are assigned to channel 2, etc.
Each channel has up to 16 IDs (0-15)
Single-Bus JBOD
Lower left and upper right ports (of JBOD) are connected with SCSI jumper cable.
The host is connected to lower right port of JBOD.

Split (Dual)-Bus JBOD
Half of disk drives (on JBOD) are assigned to one channel and second half to another.
This is convenient for RAID1-mirror configuration.
Lower left and lower right ports are connected to the host.
