Installing Novell Netware 69
Intel RAID Controller SRCU31 and Non-ASPI Compatible
Controllers
If an Intel RAID Controller SRCU31 is operated under NetWare together with another
controller/host adapter which does not support the ASPI standard, SCSI raw devices cannot be
operated on both controllers (tapes, CD-ROMs).
In general, NetWare gives preference to controllers which support the ASPI Standard (for example,
Intel RAID Controller SRCU31, Adaptec
†
). As soon as “aspitran.dsk” is loaded (auto-loading
module) tapes and CD-ROMs on the ASPI non-compatible controller are no longer recognized. To
avoid this problem, the “aspitran.dsk” file can be deactivated via a modification.
To deactivate “aspitran.dsk,” find the string “ASPI_Entry” by using a Disk-Monitor in
“aspitran.dsk” (please pay attention to upper case letters etc). Modify the string by replacing “A”
with an “X” (for example, “XSPI_Entry”). The modified “aspitran.dsk” enables the operation of
raw devices on non-ASPI-compatible controllers.
✏
NOTE
After this modification, no other raw devices (tapes, CD-ROMs) are recognized on the Intel RAID
Controller SRCU31 or Adaptec.
Last Status Information
All Intel RAID Controller SRCU31 Controllers temporarily store the status information from all
hard disk drives that are connected to that controller. This information can be useful when
searching for possible causes of disk failures or interferences. The last status information consists
of a hexadecimal, 8-digit number and can be displayed via the StorCon or saved in a SAVE
INFORMATION ASCII file. The information is temporarily available in the Intel RAID Controller
SRCU31’s RAM. Therefore, it is important to check this information before switching off and
before carrying out a Reset if a disk failure has occurred or if interference was present. The last
status information is divided into controller-specific and SCSI-specific messages. A detailed
description can be found in the “laststat.pdf” file.
Adding Additional Capacity After an Online Capacity Expansion
The additional capacity resulting from an online capacity expansion of an existing array drive is
introduced to the system as a new host drive. To be able to make use of the new capacity without
having to down the server, type “scan for new devices” on the server console to recognize the new
capacity. Use “Install” to build new partitions and volumes.
