https://community.hpe.com/t5/msa-storage/hsg80-disk-i-o-error/m-p/1082651#M4843 Hi,<BR /> <BR /> I have two disk enclosures connected to an hsg80 controller. The storage is partitioned into various arrays. This hsg80 controller is connected to an IBM SVC unit.<BR /> <BR /> The svc unit reports disk errors on one of its managed disks (on the hsg80). This managed disk corresponds to a specific array of four disks, with one disk on each side of the two enclosures. No other errors are shown, and the disks are showing green.<BR /> <BR /> I guess that one of the disks is starting to fail and the svc software has caught the error before the hsg80, as I have run the fmu on the controller and nothing is shown. <BR /> <BR /> Can you suggest other things I can try to find where the problem lies?<BR /> <BR /> Looking forward to your replies.
