You receive iDRAC not ready error when trying to open iDRAC or change network settings on Dell Server blades
The resolution I found was
- Power off the problematic server.
- Pull it out from blades Enclosure.
- After you put it back and server boots it should solve the problem.
If you experience such problem .
For example
" Enclosure, "1", has detected that a power supply in bay 6 has changed from status OK to Unknown."
Go to HP and download latest HP BladeSystem c-Class Onboard Administrator Firmware
Note:Before updating enclosure firmware be shure to update all blades ILO to resent version.
If you skip that step you may experience with disconnection problems when connecting to blades.

This is Common problem in HP server blades default configuration. The default setting locks ILO and you see that message till you reset ILO.
To fix the problem go to Problematic Blade >ILO >Web administration
Remote console>Settings and change Remote Console Acquire to Enabled
