Drive repair for NVMe initialization failure
If an NVME drive fails to initialize, the drive that is connected to PERC can be corrected in HII. The NVME initialization errors in
the drives are listed as correctable and non-correctable errors in HII.
Repair drives with correctable NVMe initialization errors
Repair the drives with correctable NVMe initialization errors in HII to enable the drives to work properly.
About this task
Repairs can lead to permanent data loss in drives. Also, certain types of repairs can take a long time.
Steps
1. Log in to HII.
2. Go to Main Menu > Hardware Components > Enclosure Management.
The drives with correctable and non-correctable errors are listed.
3. Select the drive and click Repair.
If the repair is successful, the drive is listed under physical drives and removed from the correctable error list. If the drive
has other correctable errors, the drive is listed again in the correctable errors list.
4. If the repair is not successful, click Repair again.
NOTE: In case you want to stop the repair, stop the repair from the Ongoing repairs list.
If the error is still not resolved or if the drive has other non-correctable errors, the drive is moved to the non-correctable
error list.
Opal Security Management
Opal Security Management of Opal SED drives requires security key management support. You can use the application software
or The Integrated Dell Remote Access Controller (iDRAC) to generate the security key that is set in the Opal drives and used as
an authentication key to lock and unlock the Opal drives.
Hardware Root of Trust
Hardware RoT (RoT) builds a chain of trust by authenticating all the firmware components prior to its execution, and it
permits only the authenticated firmware to perform and be flashed. The controller boots from an internal boot ROM (IBR) that
establishes the initial root of trust and this process authenticates and builds a chain of trust with succeeding software using this
root of trust.
1 MB I/O
PERC 11 controllers support a 1 MB I/O feature; if the capacity of I/O frame is greater than 1 MB, the I/O frame is broken into
smaller chunks.
Auto Configure RAID 0
Auto Configure RAID 0 feature creates a single drive RAID 0 on each physical disk that is in the ready state. For more
information, see Auto Configure RAID 0.
Auto Configure behavior
Auto configure behavior automatically configures unconfigured drives during reboot and hot insertion. As per the setting,
unconfigured drives will be configured as per the option; but the configured drives will remain unaffected. PERC 11 supports Off
and Non–RAID settings.
