partitions rz29l-aa

[Eduardo Avila]

The disk is rz29l-aa, i have other disk in my system (AlphaServer 400/233) and the system recognize the disk rz29l-aa the problem is partition, how changue the partition? in disktab not exist the entry for the rz29l-aa...

[Venkatesh BL]

Can you re-state the problem in english?

Thanks,
blv

[Johan Brusche]

Eduardo, can you please run:

su -
/sbin/scu scan edt
/sbin/scu show edt

Is the disco visible in the show output ?
Suppose the new RZ29L is on bus 1, target 4, then do the following:

cd /dev
./MAKEDEV rz12

You should now be able to label the disk with:

disklabel -rw rz12 RZXX

Rgds,
Johan.

I have rz29l-aa disk, but not exist entrie in disktab file, s.o. Tru64 Unix 4.0F, then i can't partition.

[Fedor Poradovsky]

if you will use
disklabel -rw rz12 RZXX
then RZXX means, that it unknown disk,
generic disk. As I remember its geometry
will be set acording scu (you can look
at it an create own disktab entry), and
default partition layout.

the Johan's reply contained this command.
I send you only note disk type selection.

Best Regards
Fedor

Eduardo,

you are talking about a rz29l-va?
There is no rz29l-aa.
You added only one disk and no controller, right?
What kind of controller are you using?
Check on cabling and termination.

greetings,

Michael

Eduardo,
do not search rz29l-aa. the -aa means only packaging and interface, in this case internal disk. The relavant information is rz29l. It is in disktab on Tru64 4.0F and you can than write command
disklabel -rw /dev/rrz??c rz19l

To restate more clearly.

In V4.0F and higher, /etc/disktab is obsolete, not used & useless.

The disklabel command gets it's information about the geometry and capabilities of the disk via scsi inquiries towards the device itself.

ok... this is scu

Hi,

I found the disk now. Is the disk on bus 1 target zero the disk you hope to see? Can you confirm that the disk is still operational?

greetings,

Michael

[Johan Brusche]

So, now do a " file /dev/rrz1c". If you do not have rrz1c then do "cd /dev ; ./MAKEDEV rz1", then do "disklabel -rw rz1 RZXX"

Terminado...

Johan.

Johan...
ok, this is fine.
this is the partition:
type: SCSI
disk: RZ29L
label:
flags:
bytes/sector: 512
sectors/track: 113
tracks/cylinder: 20
sectors/cylinder: 2260
cylinders: 3708
sectors/unit: 8380080
rpm: 7200
interleave: 1
trackskew: 9
cylinderskew: 9
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0

8 partitions:
# size offset fstype [fsize bsize cpg] # NOTE: values not exact

b: 401408 131072 unused 0 0 # (Cyl. 57*- 235*)
c: 8380080 0 unused 0 0 # (Cyl. 0 - 3707)

h: 3911344 4468736 unused 0 0 # (Cyl. 1977*- 3707)

how can change the partition?

[Michael Schulte zur Sur · Accepted solution]

Hi,

disklabel -r rz1 > /tmp/label.rz1
vi /tmp/label.rz1
change the offset and length of the partitions.
disklabel -R rz1 /tmp/label.rz1

greetings,

Michael
