Rp7420 Upgrade

Dear All,

We have a RP7420 Machine with this configuration.

(1)Npar0 has one cell with 4 CPUs, 16GB Memory, 8 I/O slots, one core I/O.
(2)Npar1 has one cell splitting into two V-Pars, each with 2 CPUs, 4GB Memory and 4 I/O slots, one core I/O.

Here is the desire configuration information.

1. Delete both Vpar's.
2. Merge Npar1 into Npar0, and make one single primary Partition.

Partition Npar0 should have this configuration after upgrade.

1.Number of cells =2 , each cell has 8 CPU’s 32GB RAM
2.I/O Slots = 16
3.Core I/O = 1

Kindly advice the appropriate action for this activity.

Re: Rp7420 Upgrade

e.g

cell1 -- 2 vpars -- serv1&serv2
serv1>vparmodify -p serv2 manual
serv1>shutdown -h
serv2>vparremove -p serv1
serv2>shutdown -h
boot thru hpux without vpmon
serv2>rm vpdb
serv2>parremove -F -p1 (partition number)
serv2>shutdown -R -H


From the CELL0
serv0>parstatus -A -c
list the available cells (Unassigned cell)
serv0>parmodify -p# -a0:base:y:r1
serv0>shutdown -R

Those are the steps to be followed

Re: Rp7420 Upgrade

Thanks Aurn for quick reply,
I have confussion, please clear it.

From the CELL0
serv0>parstatus -A -c
list the available cells (Unassigned cell)
Suppose here we will have 2 cells with 64GB RAM,16CPU's and I/O cage, So how i will assign them?

serv0>parmodify -p# -a0:base:y:r1
serv0>shutdown -R

One more thing, for adding CPU's memory in cells how much down time required?

Thanks,
Saqi

Re: Rp7420 Upgrade

Hi Saqi,

You could do this:

1. Shutdown both vpars
2. Shutdown Npar1

3. From Npar0:

# parremove -p Npar1 -F
# parstatus
(check available cells if there isn't any reboot Npar0 with shutdown -R)

# parmodify - p Npar0 -a 0/1::::
# shutdown -R

6. Npar0 should have 2 cell and 16 I/O slots
