Hi,

You can see the current volumegroup configuration from your hp-ux with the command

vgdisplay -v

Re: xp128 in hp-ux

Hi,

Well there are quite a few ways of determining the disks/PVs per VG:

1. vgdisplay -v vg_name | grep "PV Name"
2. strings /etc/lvmtab
3. view /etc/lvmpvg

Re: xp128 in hp-ux

If installed, you may use commandview xp to review the array configuration.
Another possibility is to run xpinfo and compare the devices with the used devices shown in vgdisplay -v.

Hope this helps!

Torsten.

Re: xp128 in hp-ux

I found two diffrence in xp array.
one system has 400G surplus capacity and the other system hasn't.
system A and B has 3 alternative links.
SYSTEM A is like this -
/dev/rdsk/c17t13d6 e8 0d ee CL1B 00:f5 OPEN-E
/dev/rdsk/c16t13d6 cd 0d ee CL2A 00:f5 OPEN-E
/dev/rdsk/c18t13d6 cc 0d ee CL2B 00:f5 OPEN-E
/dev/rdsk/c13t13d6 ef 0d ee CL1A 00:f5 OPEN-E
/dev/rdsk/c16t13d7 cd 0d ef CL2A 00:f6 OPEN-E
/dev/rdsk/c17t13d7 e8 0d ef CL1B 00:f6 OPEN-E
/dev/rdsk/c18t13d7 cc 0d ef CL2B 00:f6 OPEN-E
/dev/rdsk/c13t13d7 ef 0d ef CL1A 00:f6 OPEN-E




/dev/rdsk/c16t15d6 cd 0f fe CL2A 1f:f0 OPEN-E
/dev/rdsk/c17t15d6 e8 0f fe CL1B 1f:f0 OPEN-E
/dev/rdsk/c18t15d6 cc 0f fe CL2B 1f:f0 OPEN-E
/dev/rdsk/c13t15d6 ef 0f fe CL1A 1f:f0 OPEN-E
/dev/rdsk/c17t15d7 e8 0f ff CL1B 1f:f1 OPEN-E
/dev/rdsk/c16t15d7 cd 0f ff CL2A 1f:f1 OPEN-E
/dev/rdsk/c18t15d7 cc 0f ff CL2B 1f:f1 OPEN-E
/dev/rdsk/c13t15d7 ef 0f ff CL1A 1f:f1 OPEN-E

SYSTEM-B is like this.


/dev/rdsk/c14t15d6 e2 0f fe CL1D 1f:f0 OPEN-E-CVS 00020927 --> ì ¬ì  ê³µê° 8G (í ë ì 1ê¸°ê° ì ©)
/dev/rdsk/c16t15d6 cb 0f fe CL2C 1f:f0 OPEN-E-CVS 00020927
/dev/rdsk/c11t15d6 e4 0f fe CL1C 1f:f0 OPEN-E-CVS 00020927
/dev/rdsk/c15t15d6 ca 0f fe CL2D 1f:f0 OPEN-E-CVS 00020927
/dev/rdsk/c16t15d7 cb 0f ff CL2C 1f:f1 OPEN-E-CVS-CM 00020927
/dev/rdsk/c11t15d7 e4 0f ff CL1C 1f:f1 OPEN-E-CVS-CM 00020927
/dev/rdsk/c14t15d7 e2 0f ff CL1D 1f:f1 OPEN-E-CVS-CM 00020927
/dev/rdsk/c15t15d7 ca 0f ff CL2D 1f:f1 OPEN-E-CVS-CM 00020927

system B don't have OPEN-E type disk any more.
why each two system are different?
and I don't know rhe meaning OPEN-E-CVS and OPEN-E-CVS-CM are having.

Re: xp128 in hp-ux

Be careful too to make sure some of your LUN are not being used for raw disk purposes. HP offers a class on the XP arrays and I really think it is needed to understand the array and Business Copy Volumes. Otherwise you have much reading to do.

Re: xp128 in hp-ux

OK.got it.But why is different to see disk capacity between two systems.
It is configured with MC/SERVICEGUARD.
Ecept using disk, A system is seen as 400G capacity, B system doesn't~
I just want to know this.

Re: xp128 in hp-ux

The xp128 can selectively present LUNs to different hosts. The XP's LUN security will look at the WWN of the host's HBAs and and based on what is entered into the LUN security will or will not let the host even know that the LUN is there. I would check that first. Then second execute ioscan on each host to confirm that all LUNs are seen on both systems. You may need to install device files (insf -e), if you have new LUNs or LUNs without a /dev/rdsk entry.
