It shows the installed drives, model, and status. In addition, you can see what  action is performed, for which pool the drive is working, and the mounted physical volume. If  the status is not idle, the logical volume that is in use also is provided.  Figure 11-39 shows a sample output of this command.

This data is used by  Grid Resiliency function, which was supported since R4.1.2. This command is supported only with a grid configuration and not with a stand-alone cluster. This command helps you monitor the health of clusters in the grid communication, which  provides diagnostic information for handshake between two clusters in the grid. The  LI REQ,complib,DIAGDATA,SHOW,{AVG|MAX|MIN|TMO|ERR}  command is used to display the  average, maximum, or minimum elapsed time, or the timeout or error count for handshaking  of all clusters in the grid.
