Unsaved Data in the Controller Cache
The Dirty Cache LED informs you that there is data in the cache that has not
been saved to non-volatile memory. Such data is sometimes called “dirty,” not to
suggest it is corrupted in some way but because it has not been saved to a disk
drive.
Figure 23.Dirty Cache LED
If there is unsaved data in the controller’s cache, the Dirty Cache LED shines
amber. During this time, do NOT power down the VessRAID. Wait until the LED
goes dark.
VessRAID Does Not Boot
The most common cause of a VessRAID not booting is when power to the
subsystem was interrupted during a firmware flash.
See “Chapter 8: Maintenance” on page 313 for more information about firmware
flashing.
If Rescue Mode is enabled and you have a USB drive with a boot partition, you
can boot the VessRAID from the USB drive.
1. Power down the VessRAID.
2. Attach the USB drive.
3. Power up the VessRAID.
4. Monitor the boot sequence from a serial connection.
