Configuration Issues
C-1: A secure erase must be performed on the drive, but RSSDM is prompting for a
password; what is the password?
The password for performing a secure erase on the drive is
ffff
(lower case).
C-2: How is write cache enabled?
In support pack releases 134 and later, the RSSDM CLI and GUI each provide an option
to enable the drive write cache. Because the drive does not contain a capacitor-backed
write cache, data may be lost and/or UECC errors may occur if the drive encounters an
unexpected power loss when the write cache setting is enabled.
If you plan to enable write cache to improve performance, make sure to review the
warning message that appears in RSSDM when you attempt to enable this option. Addi-
tionally, make sure no surprise (unexpected) power-down events occur on the system. If
you are uncertain whether these surprise power-down events may occur, leave the set-
ting in its default disabled state.
Note:
On the P420m drive, which contains a capacitor-backed write cache, the write
cache setting is permanently enabled and cannot be disabled.
C-3: Performing a SANITIZE BLOCK ERASE operation on an NTFS partition while run-
ning I/O stress tests does not abort the I/O operations
If Iometer or other Windows-based I/O stress tool is running on an NTFS-formatted
partition and while the I/O is in progress a SANITIZE BLOCK ERASE is performed using
RSSDM, the I/O operations do not abort.
This is expected behavior. To avoid this behavior, unmount the NTFS partitioned vol-
ume before executing the SANITIZE BLOCK ERASE command using RSSDM.
C-4: The system hangs when issuing an I/O during a SANITIZE BLOCK ERASE opera-
tion
Issuing I/Os during a SANITIZE BLOCK ERASE operation may cause abort conditions
while the driver queues incoming requests while it waits for the drive operation to com-
plete. After the drive operation completes, the driver will issue all queued I/O requests if
there are any remaining following the operation. The file system and partition table will
no longer be present after this operation completes. This is expected behavior. The da-
tastore should be unmounted before issuing the SANITIZE BLOCK ERASE operaiton.
Performance Issues
P-1: The drive is not responsive and the LED is not solid green
Check the LED codes in Table 2 (page 50).
P-2: Performance tests run on the drive are lower than the values specified in the data
sheet
Follow these steps to optimize the performance of the drive:
1. Verify you are following Micron's recommended SSD testing flow when running
performance tests on the drive. See Micron's Best Practices for SSD Performance
Management technical marketing brief for details on the testing flow.
