Frequently Asked Questions
What kind of disk drives can I use with J610s and J310s?
The J610s and J310s support 3.5-inch Serial Attached SCSI (SAS) disk
drives.
How can I tell when the J610s or J310s unit has fully booted?
When the J610s or J310s unit is fully booted up, the Power and FRU LEDs
will light up green. If a disk array is present, the Logical Drive LED will light
up green also. The heartbeat LED blinks green once every 3 seconds if one
I/O module is installed, or twice every 3 seconds if two I/O modules are
installed.
How can I tell my CLI connection is to the primary default I/O module?
After you establish the CLI connection, type Enclosure and press Enter. Look
at the top of the display for an item called I/O Module Role. If the Role is
Active, you are connected to the default primary I/O module. If the Role is
StandBy, you are connected to the default secondary.
What happens if a disk drive fails?
Depending on the nature of the failure, the failed drive the drive might not
appear in the CLI, or the failed drive might appear with an error, when you
run the enclosure command or the link command. See the VTrak J610s,
J310s Product Manual on the CD for more information.
Can I hot-swap a failed drive with a new one?
Yes. Disk drives are hot-swappable on the J610s and J310s units.
Can the J610s and J310s run using just one power supply?
Yes, it is possible to run J610s and J310s unit on a single power supply.
J610s and J310s units ship with two power supplies. The J610s or J310s
unit will continue running if one of the power supply fails. But deliberately
leaving one power supply off negates this advantage.
In addition, leaving one power supply off reduces air flow through the J610s
or J310s enclosure and can contribute to overheating. Always switch on both
power supplies.
