[Michael Schulte zur Sur]

Hi,

it looks like a disk is getting bad blocks and the controller is using bad block replacement.
Device Locator x000106 Port = 6.
Target = 1.
LUN = 0
Write Error Recovered with Auto
Reallocation

greetings,

Michael

[Ivan Ferreira]

Also, consider that the message is low priority:

Event severity 5. Low Priority


Nothing to be worried about. It's more an informational message.

[Johan Brusche · Accepted solution]

ONE low priority event is probably not to worry about, however MANY of the same low priority are a sign that a HIGH priority (broken disk) is bound to happen --->(RAID-LUN in degraded mode or unuseable JBOD)
