How to change raid controller driver ? (hardware change)
Hello
I'm trying to virtualize an instance of Sco Unix 5.0.5 in VirtualBox (called VM-A) , but sco I have problems set to launch with the new raid controller .
The physical machine has a raid controller adaptec (alad driver) but VirtualBox uses buslogic (blc driver)
What I'm doing is starting a Sco Unix 5.0.5 guest (called VM-B ) installed from the beginning (to use blc driver), then the second record mount as physical pc (generated with dd) .
For reference call diskB: VM-B guest disk and diskA : used by VM-A (generated with the dd command from the physical computer ).
The steps performed are:
mount /dev/rootmay /mnt/rootmay # mount diskA
mount /dev/bootmay /mnt/rootmay/stand # mount of diskA boot
chroot /mnt/rootmay /bin/sh # chroot on diskA
mkdir fd0
mount / dev/fd0 / fd0
/etc/btldinstall /fd0 # I install driver blc
edit /etc/conf/cf.d/mscsi of the form:
blc Srom 0 1 0 0
blc Sdsk 0 0 0 0
These steps have made reading and collecting things in different forums , I'm not sure if they are all necessary steps are correct or if all (I have been layered to find documentation )
Like something strange , the file /etc/default/scsihas in diskA no line ' blc " BusLogic Multi Master Adapters" ' but diskB if so, what makes me assume that I'm doing things right ,
Then when I start the VM-B (primcipal diskA y secondary diskB) seems to start the kernel VM-A because I changed the name of the hostname , but will not let me login (as it starts inconsistent and buggy)
when I start the VM- A, still fails stating the eror :
WARNING : no root disk controller hd
H iinit
Panic: srmountfun - Error 19 mounting rootdev ( 1/42 )
Error 19 opening dumpdev ( 1/41 )
Dump not completed
What am I doing wrong? you can change the driver blc alad by the way I'm doing ?
Thanks for getting up here ..

NAME
scsimgr_fcd - Fibre Channel interface driver fcd plug-in for scsimgr
DESCRIPTION
The Fibre Channel interface driver plug-in for implements management operations specific to fibre channel HBA controllers bound to driver
is the native HP-UX Fibre Channel interface driver that manages fibre channel devices.
The plug-in handles the following operations for driver
o Get, set and save per driver instance attributes.
Commands
The user can explicitly send the following commands to the driver plug-in by specifying the instance#> HBA controller hardware path>
instance#> option:
Displays information on attributes.
Saves value of attributes in a persistent store.
Sets values of attributes.
Refer to scsimgr(1M) for the syntax of these commands.
automatically invokes the plug-in to perform the driver specific part of the operation when the operation applies to per driver instances.
Attributes
The following table lists driver specific attributes. For details on the concept of attributes refer to scsimgr(1M).
Note: The following conventions are used:
o RO is Read Only.
o RW is Read Write.
o string is an array of characters.
---------------------------------------------------------------------
Object Attribute Name RO/RW Type Description
---------------------------------------------------------------------
Controller sym_port_name RW string Symbolic Port Name for
fibre channel HBA con-
troller
Default: <host-
name>_fcd<instance#>
---------------------------------------------------------------------
sym_node_name RW string Symbolic Node Name for
fibre channel HBA con-
troller
Default: <hostname>_HP-
UX_<os release version>
---------------------------------------------------------------------
EXAMPLES
Display all attributes for HBA controller with DSF /dev/fcd1:
Get HBA controller symbolic port name for DSF /dev/fcd1:
Get HBA controller symbolic node name for hardware path 0/2/1/0:
Set HBA controller symbolic port name for DSF /dev/fcd1 to fcd1_port:
Set HBA controller symbolic node name for class fc and instance 8 to fcd1_node:
Save HBA controller symbolic port name for DSF /dev/fcd1 as fcd1_port:
Save HBA controller symbolic node name for hardware path 0/2/1/0 as fcd1_node:
