HP D7171A - NetServer - LPr Software Install Manual page 9

Configuration #2:
Four HP NetRAID disk array cards
Two NIC's
To resolve this issue ServicePack 29 is required. You can obtain this update by contacting your
IBM representative.
Tip 16) Specific to E Series NetServers: How to boot from a NetRAID adapter
while a 2910Bui SCSI card is present on the system
The following steps are involved during system boot to install boot partition on NetRAID
adapter disk arrays.
1. Disable Host Adapter BIOS by using <Ctrl A> during boot-up. Host Adapter BIOS
settings are within SCSI Select utility -> Advanced Control Options.
2. Apply consideration number one listed below to keep the appropriate boot order.
Tip 17) IRQ Sharing can cause system hangs
Avoid sharing IRQ's between NICS, between HBA and DAC to avoid hang problems caused
during heavy system usage.
Tip 18) Adaptec driver AIC7870.ADD 133496 12-Jan-1998 or later is required
for 2940UW with rev B chip set
We have seen intermittent hangs caused by the AIC7870.ADD driver. The problem can happen
with any version of the Adaptec adapter that uses this driver. However, the problem is more
pronounced with an Adapter that has Rev B of the 7870 chip. Hewlett Packard recommends that
you use the driver dated 12-Jan-1998 or later.
Tip 19) Configuring IDE drives as boot device
When installing an IDE drive on your E series NetServer you must follow the following notes.
1. You must order an IDE cable 5183-2103 which is not included with the system.
2. The IDE drive must be the boot drive.
3. The boot partition must be less than 2GB.
4. It is possible to install a boot-manager utility on the IDE drive and the target NOS on a SCSI
drive.
5. When Installing OS/2 on a Quantum 4.3GB (Fireball) drive the drive capacity reported by
FDISK is 57MB. IBM is aware of this issue. Please contact IBM's web site for a driver
update. This issue was experienced with driver IBM1S506.ADD 54326 26-Jan-1996.
