Hi Nejad

pvdisplay

vgdisplay -v /dev/

will help you,

your system sees from two paths c13 and c14.
1. if you using lvm ;
strings /etc/lvmtab should noy contain that disk .
pvdisplay /dev/dsk/c13t1d3 should not give you disk you are trying to add .
2. if you are using vxvm
vxdisk list output should noy give you that disk name.

note that c13t1d4 and c14t1d4 are the same disk.

[Patrick Wallek]

While vxdisk and pvdisplay will show you if the disk is in use by VxVM or LVM, NOTHING other than good documentation will show you if the disk is in use as a raw disk.

Raw disks, where you talk directly to the disk via the /dev/dsk or /dev/rdsk device file, are sometimes used for databases.

YOu absolutely MUST keep good documentation on the use of your disks.

Hi
i am increased this disk /dev/rdsk/c10t1d5 from SAN storge by 50GB but the size of the mount point on this disk is not change.
# bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg09/lvol1 136192000 48958608 86552136 36% /u09
and
# diskinfo /dev/rdsk/c10t1d5
SCSI describe of /dev/rdsk/c10t1d5:
vendor: HP
product id: HSV210
type: direct access
size: 31457280 Kbytes
bytes per sector: 512
how to solve this problem?
thanks

hopps ; you must not change disk size on storage . you should create a new virtual disk and present to this host. after creating disk devices with ioscan fnC disk; insf . you should extend vg by vgextend and extend lv by lvextend and lastly extendfs filesystem. if you have online jfs license, you can extend filesystem by fsadm instead of extendfs.

mathmad.

Hi Nejad


When you run bdf it will display your VGs and their LVs and which LV mounted on which mount point like that

/dev/vg09/lvol1 136192000 48958608 86552136 36% /u09

/dev/vg09 is VG

and when you run the following command

vgdisplay -v /dev/vg09

it will display the VG's physical disks (or LUNs)


You must run vgdisplay with each VG to find which disk belong to which VG

In vg display output, you can also see how many physical extent free for each disk

And you must not modify LUNs on storage side, you must create new virtual disk and you must add to vg that you wanted to extend. Howewer 11.31 has new features about vg management.

I think you are note familiar with VG administration, so you should consult your HP support representative. And my recommendation is you must backup before VG operations.

Hi
thanks
but the 50GB Where go? and how find it
and i Manage to retrieval the 50GB to SAN.
thanks and best regards

[Murat SULUHAN]

Hi Nejad

In fact you have got trouble with the LUN
Can you submit your UX release info.

Murat


Don't forget the points

[Mousa55]

Hi
i want to select point but all it hidden
thanks

[Murat SULUHAN]

Hi Nejad

"i am increased this disk /dev/rdsk/c10t1d5 from SAN storge by 50GB but the size of the mount point on this disk is not change."

If you run HP-UX 11.23 or 11.31 use vgmodify.

man vgmodify

For 11.11 backup the data, reduce the disk from the VG, (remove VG if needed), create a new PV and add it to the VG. Restore your data.

Better solution: Don't increase the vdisk size, but create a new vdisk.

[Mousa55]

Hi
i am create a new virtual disk, but there error in create VG
# vgextend vg09 /dev/dsk/c17t2d0
vgextend: Physical Volume "/dev/dsk/c17t2d0" contains no LVM information

i am execute insf -eH command
what is the LVM information and solution this problem
thanks

[Torsten.]

You must create a physical volume before extending the VG:

# pvcreate /dev/rdsk/c17t2d0
# vgextend ...

[Murat SULUHAN]

Hi Nejad

Did you prepare your just created disk with pvcreate command like following line

pvcreate /dev/rdsk/c17t2d0

Did you solve the previos problem?
