MC Level |
Change Description |
|
|
C51D |
Code change made to fix a problem only
seen in drives used in multi-initiator/HA environment, drives with previous
level of code used in this type of environment caused performance degradation
if one system was rebooting while the other system was operational. |
|
|
C51C |
-Added
DWD (Dropped Write Detect) function for reliability enhancement (this change
is transparent to users), drive becomes “Write Protect” when DWD offline test
fails. -Disabled
Raid manager Format Certification (Raid manager Format time is the same as
AIX Diag format now) -Enabled
feature to clear contingent allegiance with tagged command (fixed busy status
problem) |
|
|
C51A |
Fixes and enhancement for drive to work
with the new "PCI-X Ultra 320 Dual Channel SCSI Adapter" and "PCI-X
Dual Channel SCSI RAID Adapter". This level of code supports 522
Bytes/sector format, and it is the minimum requirement for this drive to
function properly with new adapters. |

C518 |
Initial Released version |
===============================================================
Approximately 20 minutes if
drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if
drive is not part of rootvg(using concurrent
diagnostics).
2.2.1 SCSI
Drives attached to SCSI Controllers and
PCI-X RAID Adapters
To
see the drive type and current microcode level, Execute the following command:
lscfg -vl
hdisk* |pg
; For drives NOT configured for RAID
lscfg –vl pdisk* |pg ; For
drives configured for RAID
Example of the info on a
73 GB SCSI hard disk:
lscfg -vl hdisk1

If the data returned in the "Part
Number" field matches the one listed above AND the "ROS Level and
ID...." field of that data is below "43353144"
, this microcode applies. If this level is already installed then
the "ROS Level and ID...." shows:
"43353144".
Note: Drive microcode level is displayed in Hex value of ASCII charactors in VPD data. Each alpha-numeric ASCII charactor converts to a 2-digit hex number. For
example in VPD displayed above, 43 Hex= ASCII chractor
"C";
35 Hex= ASCII charactor "5" ; 31 Hex=ASCII charactor "1";
44 Hex=ASCII charactor "D", therefore the microcode level is C51D. Also note that last
four digits of field "Device Specific.(Z1)........1109C51D"
shows drive's microcode level.
At AIX command line, type:
Diag
Select "Task Selection" from diagnostics menu.
Select "PCI RAID Physical Disk Identify"
Select SCSI RAID Adapter (press enter, then F7 to Commit)
This will display the Vital Product Data for Physical
Disk drives attached to the RAID adapter.
===============================================================
a) Make a directory on an AIX system to
receive the AIX format file.
Enter: mkdir
/tmp/fwupdate
b) Transfer the AIX format file to the /tmp/fwupdate
directory (using "Save as ...").
You'll see the filename is 73lpx15.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x 73lpx15.bin
./ 73lpx15.bin
[Don't overlook the periods (.) in the above command.]
The directory 73lpx15 with microcode files
listed in section 1.1 will be added to /tmp/fwupdate.
d-Enter the following command to copy
the microcode files to " /etc/microcode " directory
:
cp /tmp/fwupdate/73lpx15/ST*44
/etc/microcode
e- Do this step if you want to copy microcode
files onto a diskettes.
Note: Don't overlook the complete path of microcode files,
AIX Diag microcode download
will not work if files are not copied with complete path onto thediskette.
Enter the following
command to copy microcode file(s) onto a floppy diskette:
ls /etc/microcode/ microcode_filename | backup
-ivf /dev/rfd0
where microcode_filename is
microcode file that is needed, for example:
ls /etc/microcode/ ST33675.53583133.43353144 | backup -ivf /dev/rfd0
Note: The
instructions that follow are specific AIX commands. AIX commands are CASE
(lower and upper) SENSITIVE, and must be entered exactly as
shown, including filenames.
a)
Make a directory on an AIX system to receive the RPM format file.
Enter: mkdir
/tmp/microcode
b)
Transfer the RPM format file to the /tmp/microcode
directory (using "Save as ...").
You'll see the filename is 73lpx15-c51d-AIX.rpm
c)
Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv
--ignoreos 73lpx15-c51d-AIX.rpm
|_ Note two
“dashes”
The
file size and checksum will be verified.
The microcode
files will be added to /etc/microcode/
Copy
microcode updates from the CD-ROM to standard locations on your local disk:
1.
RPM packaged microcode files will be copied to "/tmp/microcode/RPM"
2. Microcode files will be copied to /usr/lib/microcode
Notes:
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated directory
or file then the user will be prompted for a new location.
========================================================
Warning: Do not power off the system or the drive during microcode download as
this may permanently damage the disk drive
NOTE: Please save current and older versions of the microcode update files
in case you need to restore your system.
Caution: The microcode download process is nondestructive to the hard disks; however,
as a precaution, ensure that a backup operation has been performed on the
affected systems PRIOR to the microcode installation.
Can microcode be installed Concurrently?
AIX level 5.1 and above supports concurrent microcode download on all drives,
including drives that are part of rootvg.
AIX level 4.33 and below does not support concurrent microcode download if
drive is part of rootvg, microcode download can ONLY
be performed in service mode(stand alone) using diagnostics CD. If disk is not
part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.
Is system reboot needed to activate the
microcode: Yes if stand alone
diagnostics is used, NO if concurrent diagnostics is used.
Installation Time: Approximately 20 minutes/drive if stand alone
diagnostics is used(using Diagnostics CD);
Approximately 5 minutes/drive if consurrent
diagnostics is used.
