Hardware

Hi there,
Have noticed these errors in dmesg log and seems like during this period of errors we had our systems have a very low transfer rate.

I have 3 sets of erros to dig into.

[1] I did some search and found a similar error and had a patch for the specific device ...(reference http://sunsolve.sun.com/search/document.do?assetkey=1-26-101771-1). Errors are attached below

[2] SAM-FS critical device error. Not sure on if this is critical, and how to go about finding the source of the problem.

[3] output of iostat -En ....showing 2 hard errors. is this the source of all problems above ???

Thanks for any help you can provide!!!
