HI

I want to replace one of the two redundant controllers.
Can I remove it during operation of the system?
I found the description of the HP StorageWorks Modular Smart Array500 Generation 2 Storage System Maintenance and Service Guide:

to remove redundant conntroler:
1.Determine if the controller configuration supports hot-plug cache replacement:
−
If the storage system is equipped with a single controller, power down the storage system (on page9).
−
If the system has redundant controllers and the replacement cache is a different capacity than the failed cache, power down the storage system (on page9).
−
If the system has redundant controllers and the replacement cache is the same capacity as the failed cache, proceed with step 2.
2.Remove the controller ("Modular Smart Array 500 Generation 2 Controller" on page 13).
3.Remove the existing cache module.
Repeat steps 2 and 3 if the storage system has redundant controllers and the
replacement cache is a different capacity than the failed cache.
To replace the cache module:
1.Install the module in the slot....

Thanks and regards
