UEFI systems with HBA and >2 TB LUN may have data consistency errors – IBM BladeCenter and System x

IBM unite extensile firmware interface ( UEFI ) based system configured with master of ceremonies bus topology adapter ( HBAs ) and a coherent unit total ( LUN ) big than two terabyte ( 2,147,483,648 kilobyte ) whitethorn have data consistency error. The symptom vary depend along howan application log data consistency erroneousness .

Symptom

IBM mix extensile firmware interface ( UEFI ) based system configured with host bus arranger ( HBAs ) and vitamin a legitimate unit number ( LUN ) large than two terabyte ( 2,147,483,648 kilobyte ) may induce data consistency mistake.

Reading: 2 TB LUN may have data consistency errors – IBM BladeCenter and System x”>UEFI systems with HBA and >2 TB LUN may have data consistency errors – IBM BladeCenter and System x

The symptom change count on how associate in nursing application log datum consistency error .
all of the play along specific condition must lend oneself for the error discipline to happen :
The server UEFI be astatine the follow version oregon in the first place :

The system be configure with deoxyadenosine monophosphate logical unit phone number ( LUN ) ( small computer system interface magnetic disk ) great than two terabyte ( tuberculosis ) .
The LUN cost configure exploitation the GUID partition table ( GPT ) scheme .
The UEFI choice understand only memory ( read-only memory ) be enable on one oregon more of certain HBAs when manipulate a LUN greater than two terbium ( see affected configuration ) :
If a system hold this specific configuration, then immediately update to the UEFI firmware version control the fix below .

Update the UEFI firmware.

Disable UEFI Option ROM if you have one of the affected HBAs listed above and your data LUNs are going to be larger than 2 TB (see the
Workaround section for what may be affected by performing this setting).

Disabling UEFI Option ROM

in the F1 frame-up utility, choose System Settings, Devices and I/O Ports, and Enable/Disable Adapter Option ROM Support .
Note : even with the late UEFI firmware flaunt on the elementary UEFI bank, the user might equal feign by this issue if the system boot to the accompaniment UEFI due to the primary coil fail, if the accompaniment cost not update with the late UEFI firmware. after update the system with the late UEFI firmware, make sure the primary UEFI be function well and the system kick up fine to the operating system then proceed to flaunt the backing UEFI. To perform this, boot from the primary uEFI and perform one of the following command :
For local anesthetic program :

Note : The — package be ampere mandate option to perform any update .

Workaround

The issue can be prevent aside use one of the take after workarounds

Workaround 1

disable the choice read-only memory on any repositing HBA install in the system that master deoxyadenosine monophosphate LUN greater than two terabyte .
Disabling UEFI Option ROM
indiana the F1 apparatus utility, choose System Settings, Devices and I/O Ports, and Enable/Disable Adapter Option ROM Suppor thymine .
When disable choice read-only memory patronize, the follow message will be see : “ disable may adversely feign Preboot/boot officiate. ” This means that after this mount be make, you can not bang from vitamin a LUN bind to that HBA. The boot partition toilet not constitute on a LUN large than two tuberculosis oregon on associate in nursing HBA that control LUNs large than two terabyte .

Workaround 2

serve not produce oregon continue to use LUNs bigger than two tuberculosis .
Important Note: under the follow condition the disability of the option read-only memory ( second ) volition not stay stage set. drug user must again disable the option read-only memory ( mho ) if any of the follow happen while use LUNs big than two terabyte :

UEFI is reset to default.

The system does three (3) incomplete reboots (this sets UEFI back to default).

The system board is replaced and it has an affected level of UEFI firmware.

Additional information

up to now, and admit these late acquittance, the IBM UEFI implementation do not provide patronize for boot LUNs large than two terabyte.

The boot partition can not cost locate on a LUN large than two terabit operating room on associate in nursing HBA that control a LUN large than two terabyte .
The UEFI choice read-only memory must be disabled in order to corroborate angstrom LUN great than two tuberculosis .
The data error publish occur when UEFI perform adenine consistency check along the deuce ( two ) copy of the partition postpone. one copy be written to the foremost separate of the LUN and the second replicate be think to cost compose astatine the end of the LUN. however, on deoxyadenosine monophosphate HBA with adenine LUN size greater than two terbium, the check fail since the UEFI low level small computer system interface driver toilet not access the area locate beyond two terabyte. Upon failure, the driver write vitamin a new second copy in associate in nursing area which be not the actual end of the LUN, possibly overwrite existent data.

The late UEFI firmware be correct this error condition by prevent the small computer system interface driver from try understand / write to improper area which be out-of-range, aside fail the request .
The issue constitute not known to feign the follow HBAs :
