Optional configuration tasks This chapter details optional configuration tasks specific to ProLiant servers. Enabling iLO virtual serial port By default, Solaris does not recognize the iLO virtual serial port. If enabled, this virtual serial port can be used as a serial console (by appending "-B console=ttya" to the GRUB kernel line). The procedure to enable the virtual serial port can potentially cause configuration issues with Solaris. Review the failsafe mode before configuring the virtual serial port. To enable Solaris to see the iLO virtual serial port, make the following changes to /kernel/drv/asy.conf: 1. Comment out (by pre-pending a '#') the "interrupt-priorities" line. 2. Add one of the following lines, depending on which serial port has been designated as virtual in RBSU: For a virtual COM1 add: name="asy" parent="isa" reg=1,0x3f8,0x8 interrupts=0x4; For a virtual COM2 add: name="asy" parent="isa" reg=1,0x2f8,0x8 interrupts=0x3; Do not add them both (or have both uncommented). 3. Reboot. Mirroring disks with DiskSuite Solaris supports disk mirroring through DiskSuite. In this example, c0t0d0 is mirrored by c0t1d0. 1. Inspect the current partition table of c0t0d0.

Optional configuration tasks
This chapter details optional configuration tasks specific to ProLiant servers.
Enabling iLO virtual serial port
By default, Solaris does not recognize the iLO virtual serial port.
If enabled, this virtual serial port can
be used as a serial console (by appending
"-B console=ttya"
to the GRUB kernel line).
The
procedure to enable the virtual serial port can potentially cause configuration issues with Solaris.
Review the failsafe mode before configuring the virtual serial port. To enable Solaris to see the iLO
virtual serial port, make the following changes to
/kernel/drv/asy.conf
:
1.
Comment out (by pre-pending a '#') the
"interrupt-priorities"
line.
2.
Add one of the following lines, depending on which serial port has been designated as virtual in
RBSU:
For a virtual COM1 add:
name="asy" parent="isa" reg=1,0x3f8,0x8 interrupts=0x4;
For a virtual COM2 add:
name="asy" parent="isa" reg=1,0x2f8,0x8 interrupts=0x3;
Do not add them
both (or have both uncommented).
3.
Reboot.
Mirroring disks with DiskSuite
Solaris supports disk mirroring through DiskSuite. In this example,
c0t0d0
is mirrored by
c0t1d0
.
1.
Inspect the current partition table of
c0t0d0
.
Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 812 400.15MB (813/0/0) 819504
1 swap wu 813 - 1333 256.43MB (521/0/0) 525168
2 backup wm 0 - 17659 8.49GB (17660/0/0) 17801280

7 home wm 16846 - 17658 400.15MB (813/0/0) 819504
2.
Copy the partition table of the first disk to its mirror.
# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
3.
Create at least two
DiskSuite
state database replicas on each disk. A state database replica
contains
DiskSuite
configuration and state information.
# metadb -a -f -c2 /dev/dsk/c0t0d0s3 /dev/dsk/c0t1d0s3
4.
Mirror the
root
slice.
# metainit -f d10 1 1 c0t0d0s0
# metainit -f d20 1 1 c0t1d0s0
