Where to start

Hi,

My company has received an "rx2620 2x4 1.6 GHz" with HP-UX preinstalled as part of a Development System Loan agreement in order to certify our products on HP-UX.

I am new to HP-UX, but I need to understand certain concepts especially those related to using LVM. I also need to perform tasks such as identifying which lvol is mapped to which physical device or creating raw lvols on free devices.

I looked at http://docs.hp.com/en/oshpux11iv2.html, but I wasn't able to find the docs I need. (There are only White Papers under http://docs.hp.com/en/oshpux11iv2.html#LVM%20Volume%20Manager while under http://docs.hp.com/en/oshpux11iv2.html#User%20Guides there is only one item which seems to be completely irrelevant to me.) Where should I look for the documentation I need.

Thank you!

Peter

Re: Where to start

Peter,
if you complete novice to HPUX (and /or UNIX ?) I initally would recommend using the System Admin Module (SAM), which is a Graphical User Interface and allows you to perform most of the standard sys admin tasks.

Also the build-in manuals are execellent:
See "man sam" for more details.
See "man lvm" for LVM info

And, of course, you can search the forums and ask further questions !

Re: Where to start

Thank you Peter!

It appears that HP-UX does not have that kind of extensive user/administrator documentation which Solaris has (or Oracle in the database arena). Is this correct?

The trouble is that I need to handle problems like the following:

"vgdisplay" displays two volume groups (A and B) both with "Cur PV 1" and "Act PV 1". On the other hand, "pvdisplay" reports nothing for one disk and reports only one volume group for the other disk (only B). How do I interpret this? VG "A" is shown to have one active physical volume, but does not get listed for any of the phyiscal disks?

Also, on attempts at listing "Disk Devices", SAM keeps throwing me error messages like:

--------- QUOTE ---------
The command, pd_ioparser, has failed while trying to retrieve information about the device class, CTL. The stderr output from the command was:

ioscan: libIO error from update_ioconfig: Cannot create or open /stand/ioconfig
--------- UNQUOTE ---------

I've checked "/stand" (with "ls") and there nothing in there.

On the other hand, "ioscan" reports me about three disk devices (one is a DVD-Reader).

How do I proceed sort this out?

Thank you!

Peter
