Exadata: CellCLI "list activerequest" command can produce I/O hang in Storage Server

Do not miss out on applying the patch to resolve the issue described in the MOS article "(EX27) Database IO may hang when CellCLI command "list activerequest" is executed on an Exadata Storage Server" from note ID 2095255.1 so your system is not subject to this if you ever need to run the command in an Exadata machine!
