Cold install questions

Jeff Hagstrom — Thu, 23 Aug 2001 18:41:40 GMT

Guided setup: ? Specify Root Volume Group disks? and down below it says that I have 5 disks available. 1st, there is a 10 disk raid with 2 internal disks. Where does the 5 disks come from? Why doesn't it read 10 disks or even 12 disks including the 2 internal drives? ROOT VOLUME: What makes up the root volume group? and how many disks are in it? There seems to be 3 vgNN (0,1,2) with /, /opt, /stand
,/usr. Is this my volume group? /var is on vg02. Also, at the end of the install: "The total volume sizes in disk group: "vg00" exceed the available capacity by 128mb and to run instl_dbg -D -d, but which directory do I run it against?

tab into the area where the disks are and use the down arrow to "scroll" down.

I don't understand what you are refering to?

You need to select an internal disk to use as you boot disk.

...jcd...

Hi Jeff,

Are you doing a new install? Your questions seems confusing.

1. You say you see less disks than you expect
2. what kind of RAID disks do you have?
3. You say there are 3 VGs(0,1,2) with /, opt, stand, /usr and /var on vg02. Have you defined these?

Normally Root VG (contains one disk (disk1)which is mirrored to another disk (disk2). On this Root VG (which is normally called vg00, you have /stand, primary swap, /, /usr, /var, /opt, /tmp and sometimes /var/adm/sw as a different filesystem). You want to avoid user/application data in the root VG.

This is an upgrade from 10.20. We have a disk array of 10 that has 10 9 gig drives and then the 2 internal drives. This box has /stand, /, /usr, /opt is on vg00 and /var and /tmp is on vg02. Why it was setup this way, I don't no. Should all of these directories be on /vg00?

Hi,

You might want to check out the section "Managing Disks - Page 333 in the document"
http://docs.hp.com/hpux/pdf/B2355-90742.pdf
You will get a better understand of LVM.

Not sure if you already checkout the documents

Hi Jeff,

How big are the internal drives?

Also any particular reason why choosing the upgrade path rather than cold-installing. I know thats a very debatable question and you will hear lots of stories saying upgrade is fine but in my experience, cold-install is much cleaner. Not sure what your reasons are.

I am assuming that you are trying to install new OS on the system.

No of Disks: Probably you have 3 LUNs (logical units ) created on the RAID and plus 2 internal disk ...that makes total 5.

Root Volume group: You can use 1 or mutiple disks for this depending on the requirement you have. If you want mirroring then you need two disks connected to two different controller (recommended).

Hope this helps.

Hi Jeff,

Here is another excellent link

http://www.hp.com/workstations/products/unix/operating/hpux11/cookbook/cookbook.html

Btw is the RAID you are talking about (with 10, 9GB disks) an AutoRaid (12H array)?
