Unable to lvcreate / lvextend on volume groups (HP11.31)

[Mark Parsons]

Hi - We have an issue where we are unable to lvcreate / lvextend on any of our volume groups. The example I will use is from a new disk that has been supplied to us (16gb):

pvcreate /dev/rdisk/disk235

vgcreate -V 2.2 -S "4t" -s 32 vg7004 /dev/disk/disk235

vgdisplay -v vg7004:

So logical volume has been created empty!

This is happening across all the disks / volume groups (so not just disk235 / vg7004)- all lvcreate's / lvextend's are failing.

Any suggestions please?

[Torsten.]

A common mistake is to present a volume from a SAN device to a HP-UX host not specifying the special HP-UX mode (maybe in default mode or whatever).

[Mark Parsons]

Hi - thanks for the reply but we do have previous volume groups with logical volumes that are still working. Its anything that is either now being lvextended or is new and is so being lvcreated.

Are you saying that our storage team have done something in the (re)presentation of disks or is this something that we can do?

[Torsten.]

Let the storage team compare the working and non working LUNs. Presentation mode is important, thin vs. thick *may* be important too.

[Mark Parsons]

All the original luns were working at some point (which is the reason we could originally lvcreate / lvextend) but now we cannot do this - whether the luns are original or new.

I shall get our storage team to compare the lun presentaton on this server to another hpux server (where all is fine). 

However wouldnt the wrong kind of lun presentation affect pvcreate and vgcreate before an lvcreate / lvextend was required?

According to an article I just found in HP's knowledge base says that a mismatch of LVM driver versions was a culprit at one point. 

    Check the Logical Volume Manager (LVM) version with swlist and also the LVM kernel driver module:


      BaseLVM         B.11.31.1108   Logical Volume Manager

    # LVM                        B.11.31.1008 LVM
      LVM.LVM-KRN                B.11.31.1008 HP-UX Kernel support for the Logical 
      LVM.LVM-RUN                B.11.31.1003 LVM Runtime
      LVM.LVMP-DOC               B.11.31.1008 LVM Provider Documentation common to
      LVM.LVMP-LIB               B.11.31.1008 LVM Provider Library files for IPF
      LVM.LVMP-RUN               B.11.31.1003 LVM Provider runtime software common

      LVM-MirrorDisk.LVM-MIRROR  B.11.31      HP-UX support for the MirrorDisk/UX


    # what /etc/conf/mod/lvmp  
    /etc/conf/mod/lvmp:           $Revision: lvmp:    B.11.31.1003_LR 

This is the main cause. From the output above, the filesets of LVM were mixed between B.11.31.1003 and B.11.31.1008. In addition, there was a mismatched LVM driver module.

Fix:
Either re-install the BaseLVM product with the same version (B.11.31.1008) or install the latest one. At the time of this document, the latest BaseLVM version is B.11.31.1009.01. Please refer to the HP Software Depot home:

    NOTE: The installation of BaseLVM product requires a reboot.

    For this problem, the BaseLVM B.11.31.1008 was re-installed.

    After the reboot, the driver module should show:


    # what /etc/conf/mod/lvmp
    /etc/conf/mod/lvmp:
             $Revision: lvmp:    B.11.31.1108

[Mark Parsons]

We are running:

swlist | grep LVM

  BaseLVM                                       B.11.31.1009.01 Logical Volume Manager

what /etc/conf/mod/lvmp

/etc/conf/mod/lvmp:
         $Revision: lvmp:    B.11.31.1009_LR

[Patrick Wallek]

What does the following show?

# swlist -l fileset | grep LVM
