8) Once the
/vmunix
kernel has successfully booted, several kernel mod ules need to be patched. This
must be done as superuser. Enter the following commands (not including the “#” prompt):
# adb –w /vmunix
(
adb
has no prompt. Type in the next line)
ross625_vac_i0x58?XXX
(
adb
should print the next line. If not, something is wrong!)
_ross625_vac_i0x58: c0a00620 81c3e008 1000000
(Type the following line)
ross625_vac_i0x58?W 1000000 81c3e008 c0a00620
(
adb
will print the following three lines)
_ross625_vac_i0x58: 0xc0a00620 = 0x1000000
_ross625_vac_i0x5c: 0x81c3e008 = 0x81c3e008
_ross625_vac_i0x60: 0x1000000 = 0xc0a00620
(Exit
adb

A.6 Peripheral Problems
1.) Solaris 2.3 Performance
Systems: SPARCserver 600MP & SPARCstation 10
Description: ROSS has uncovered several performance related errata in Solaris 2.3. Customers may see
lower than expected performance with Solaris 2.3 while running certain applications.
Corrective Action: Get Sun patch id #101318–74 and install on your Solaris 2.3 system.
2.) Bad Disks and Memory
Systems: SPARCserver 600MP only
Description: After installing hyperSPARC upgrades some customers have reported disk and memory
system problems which were not noticed in the system prior to the upgrade. Because hyperSPARC’s
performance is as much as 4 times greater than the original configuration, memory and I/O subsystems are
exercised up to four times harder which may accelerate latent marginal quality and reliability problems in
those subsystems.
Some customers have had to replace defective or old revisions of memory SIMMs, IPI drives, IPI drive
controllers, IPI drive cables, mother boards, and other hardware. Customers should contact their
maintenance provider to obtain latest revision hardware.
Corrective Action: Make sure your SPARCserver 600MP system has up-to-date system components (i.e.,
the latest revision). Below are two system component revisions as of 5-26-94.
