怎么会这样 Fast Data Access MMU Miss
There are two common Solaris[TM] 2.5.1 or 2.6 boot problems that are similar, but
have different solutions. There is some confusion as to what solution to use for
what problem. Both problems are that systems fail to boot to a Solaris 2.5.1 or
2.6 CD-ROM or JumpStart[TM] image. SRDB documents have been written for each
problem and this is a description of each of these and how to tell the difference.
PROBLEM #1
(see also SRDB 20576)
Any system that has a 450MHz UltraSPARC(R) II CPU or the 440MHz UltraSPARC IIi CPU
will not be able to boot Solaris 2.5.1 HW 11/97, Solaris 2.6 HW 3/98 or Solaris
2.6 HW 5/98 CD-ROM or JumpStart images of these Operating Systems. It will fail
with "hme0:link down" or keyboard input multiple repeats.
These systems must be booted with a cdrom called the Operating Environment
Installation CD February 2000 (OECD), which is Part No. 704-7076-10. Booting
this OECD will then prompt for the 2.5.1 or 2.6 Solaris CD for the install
of the OS. This OECD can also be used to modify a JumpStart image to boot/load
2.5.1 or 2.6 on these systems. See the manual "Installing Solaris Software for
Selected Hardware" Part No. 806-4005-10 for procedure for modifying a jumpstart
image.
Once a jumpstart image is modified with the OECD, this image can be used to load
Solaris 2.5.1/2.6 on these systems. If the method of installation is via a cdrom,
then the OECD must always be used. The manual (included with the OECD) also
describes how to use the OECD for CD-ROM-based installs. Here is a list of the
systems affected:
Ultra 5 Ultra 10
Netra T105 Ultra 60
Netra T1120 Netra T1125
Ultra 80 Enterprise 420R
Netra T1400 Netra T1405
Ultra 450 Enterprise 220R
Only the above systems with 450MHz or 440MHz CPUs are effected by this problem.
You can check the speed of the cpu(s) by running the command ".speed" from the
OK prompt. The problem is permanently fixed by loading the most current kernel
patch. Patching the kernel to this level is one of the functions of the OECD. The
OECD actually has a Solaris 7 kernel that it boots to, then it kicks off an install
that prompts for the 2.5.1 or 2.6 cdrom for the OS install. It will load the kernel
patch during this install, so the kernel will be patched upon the first boot to
the new OS on the disk.
This CD-ROM is not included with Solaris and is usually included with the system
in the "Binary Code License" package. The OECD can be ordered by Sun personnel
from this website: http://acac.central/SAG/Templates/CD_Zero.html
NOTE: The OECD can also be used to fix the "NOTICE: Can't find driver for console
frame buffer" install/boot problem mentioned in SRDB 19271.
NOTE: The Ultra Enterprise[TM] 450 with a 480MHz CPU requires a special procedure.
See SRDB 24408.
PROBLEM #2
(see also SRDB 20149)
Enterprise Server systems that use the 400MHz UltraSPARC II with 8mb ecache CPU
module(s) will fail to boot to Solaris 2.5.1 or Solaris 2.6 cdrom (or JumpStart
image) with "Fast Data Access MMU Miss" and/or "mutex_enter: bad mutex". SRDB
20149 describes this problem and has the exact procedure to boot/load these
systems with 2.5.1/2.6.
The problem is that the kernel on the 2.5.1/2.6 CD-ROM cannot load with the
400MHz/8MB ecache CPU until the kernel patch is loaded. The workaround (seen
in the SRDB) is to run the command "limit-ecache-size" from the OK prompt before
booting to the 2.5.1/2.6 cdrom or JumpStart image. It will be able to boot the
cdrom or image immediately after this command is run. After the OS is loaded,
you will need to run this command again from the OK prompt to boot the system
until you load the latest kernel patch. Here are the systems (that potentially
have the 400MHz 8mb cache cpu installed) affected by this problem:
E3000 E3500 E4000
E4500 E5000 E5500
E6000 E6500
Only systems that have the 400MHz/8MB cache cpu(s) are affected.
Final Note:
Do not confuse these two different problems. Do not use the OECD on an Enterprise
server in the model range E3000 - E6500 (with 400MHz/8MB cache). These servers
are fixed with the limit-ecache-size workaround to boot/load 2.5.1/2.6. The
Ultra[TM] 5 - Ultra 450 group of systems (with 440/450 MHz CPU) are the ones that
need the OE cdrom to boot/load 2.5.1/2.6. |
