Re: adding new HDD alpha 4000


As an example, let's say the new drive is on SCSI-bus 3 and has target nmbr 5 (which you can verify with the scu command), then you have to do the following:

cd /dev
./MAKEDEV rz29

The rule for calculating the "29" is:
[(8 x bus nmbr.)+ target nmbr ],ie (8x3)+5

After that you will need to partition the new disk with "disklabel -rw rz29 RZXX".

Re: adding new HDD alpha 4000

Hi,

could you create a label the way Johan suggested?
Do you see the new disks?
Lets assume the following disk is a new one:
Device: BD036635C5 Bus: 1, Target: 6, Lun: 0, Type: Direct Access}
This disk for example should have the device name rz14. Verify that /dev/*rz14* exists.
The default label you can see with disklabel -p /dev/rrz14a
What type you see in this line in your output: "disk: SWXCR"
use in the command to create the label:
disklabel -wr -t advfs /dev/rrz14a SWXCR

Re: adding new HDD alpha 4000

hi all
just a clarification,
bus 0 and bus 1 are working fine.

the problem is in bus 2 which appears in >>> and doesn't appear in OS

Solution

Re: adding new HDD alpha 4000

Hi,

have you got a new controller?
run
sizer -n conf
compare /tmp/conf with your config file in /sys/conf. The name of the config file is most likely your hostname.
Please post the lines of both files from:
config vmunix swap generic
until the last contoller item.
Maybe you will have to build a new kernel to see the bus 2.

Re: adding new HDD alpha 4000

So let us guess again....
Bus #2 was never used before ?
The new drive is the only one on that bus ?
Is that scsi bus properly terminated ?
When you boot, do you see any messages on scsi2 in /var/adm/messages ? --> If, yes, please post.
Did you recently add a new SCSI-interface for that bus #2 ? -->If, yes, you must boot from genvmunix and generate a new kernel with doconfig..
