Following SYMCLI commands can be used to detect failure disk:  symdisk list -failed symdisk list –hotspare symdisk show :   The first command symdisk list-failed is for listing the failed disks which are detected in Symmetrix array.   symdisk list –hotspare is to list all the spare disks in Symmetrix. But we can also refer the information in command output for detecting spare disk invoking status. Check the Hypr volume which means the spare used/invoked. symdisk show also can verify the failed hyper for checking the Failed Disk row.
