Frequently Asked Questions
What kind of disk drives can I use with VessJBOD?
The VessJBOD supports 3.0 GB/s Serial ATA disk drives and 3.0 Gb/s SAS
drives.
VessJBOD does not support Parallel ATA (PATA) disk drives.
Can I take the disk drives from my Promise VTrak, put them into the
VessJBOD, and keep my disk array or logical drive intact?
Yes. Like VessJBOD, the newer VTrak subsystems use the industry-
standard DDF method of disk metadata, stored in the reserve sector of each
physical drive. Use the Transport function to prepare your disk drives before
moving them. See “Preparing the Disk Array for Transport” in the VessRAID
Product Manual.
Early VTrak subsystems used a proprietary method of disk metadata.
VessRAID subsystems have a metadata-to-DDF conversion feature that
converts disk drives in attached VessJBOD enclosures. To use the
conversion feature, you must restart the VessRAID and VessJBOD after
installing disk drives from an older VTrak subsystem.
Note that if you move your disk drives from the VessJBOD to an early VTrak,
the older subsystem will not recognize your disk array or logical drive.
How can I tell when the VessJBOD has fully booted?
When the VessJBOD unit is fully booted up, the Power and FRU LEDs will
light up green. The heartbeat LED blinks green once a second.
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 some errors—when
you run the link command. See page 27.
Can I hot-swap a failed drive with a new one?
Yes. Disk drives are hot-swappable on the VessJBOD.
