Dell MD3620I, MD3600I owner manual 118

All of the physical disks and RAID controller modules in a storage array share the same security key. The shared security key provides read and write access to the physical disks, while the physical disk encryption key on each physical disk is used to encrypt the data. A security capable physical disk works like any other physical disk until it is security enabled.

Whenever the power is turned off and turned on again, all of the security enabled physical disks change to a security locked state. In this state, the data is inaccessible until the correct security key is provided by a RAID controller module.

You can view the self encrypting disk status of any physical disk in the storage array from the Physical Disk Properties dialog. The status information reports whether the physical disk is:

•Security Capable

•Secure—Security enabled or disabled

•Read/Write Accessible—Security locked or unlocked

You can view the self encrypting disk status of any disk group in the storage array. The status information reports whether the storage array is:

•Security Capable

•Secure

The following table shows how to interpret the security status of a disk group.
