Description

if a Hyperswap configuration seem's actually not really supported and the returned data are not interpreted in the correct way. Teh components "vdisk" check has not enough filter possibilities and not the possibility to override the critical status with the needed variables. So i created a new vdisk-status mode to handle the status in correct way for all needs.

For the hyperswap configuration from 4 disk 1 disk is always offline:

id  name                             status  RC_name  volume_name                      function      
380 IBMi_P3_xx             online  rcrel95  IBMi_P3_xx             master        
381 vdisk286                         offline rcrel95  IBMi_P3_xx             aux           
382 vdisk287                         online  rcrel95  IBMi_P3_xx             master_change 
383 vdisk288                         online  rcrel95  IBMi_P3_xx             aux_change    

A hyperswap configuration can be identified when the column RC_name is not empty and has a value like rcrelXX.

The right logic to monitor this configuration should be:

every disk with function master_change or aux_change must be online, otherwise should be a error
one of the disks with function master or aux is allways offline, the other one is online
to indentify which of this 2 disks should be online you need to launch the lsrcrelationship command.

It's much more faster to call it generally once wihout rc_name (lsrcrelationship rcrel95 ) as 100 times with rc_name.

So this case is OK because the offline ones is not the primary vdisk of the RC

default critical status

(%{rc_name} ne "" && %{primary} == 1 || %{rc_name} eq "") && %{status} =~ /offline/i

so this means the "primary" is only checked fore RC's. for single vdsisk only the status will be checked.

The vsidk component check can be removed
