I have two EMC Clariion CX700's (which, for convenience we call CX700-1 and CX700-2) and one recently added CX3-40 in my SAN environment using fiber-switch fabric. Over the weekend, I experienced a hardware failure on SPA on CX700-1. After having it replaced by my vendor's technician and getting the SP to reboot successfully, all was fine until 2 hours later when I got another unwelcomed alert, this time it was about an uncorrectable sector (Data Sector Invalidated):
"Event Number 840
Severity Warning Host CX700-1_SPA
Storage Array APMxx SPA Device Bus 1 Enclosure 3 Disk 3
Description Data Sector Invalidated"
Since then, I've been getting the same "Data Sector Invalidated - Bus 1 Enclosure 3 Disk 3" error at least once every day. The only solution to this as I gathered from my vendor is to unbind and then rebind the LUNs on this disk as there is a good chance some of my data within the LUNs have been corrupted -- hence the uncorrectable sector error. :(
Has anyone else have this experience before? Is this a common occurrence from the Clariion CX-series product? As of now, I am still uncertain how the sector became uncorrectable and what lead/caused the data corruption.
Unrelated to this, I am also having performance issues (in particular, forced flushing) every other week. As a long-term solution, I am getting quite concerned about my SAN environment. If possible, can anyone share some of their experiences with the EMC Clariion CX-series line?
Any input is greatly appreciated!
