Hi,

I've replaced hdisk0 in a Blade server but am having problems re-enabling the mirror as it appears the configuration database is not recognising the new disk.

The first 2 steps to re-enable the mirror fail:
$ extendvg rootvg hdisk0
0516-008 extendvg: LVM system call returned an unknown
error code (-271).
0516-792 extendvg: Unable to extend volume group.

$ mirrorvg '-Q' '-m' rootvg hdisk0
0516-304 getlvodm: Unable to find device id 00000000000000000000000000000000 in the Device
Configuration Database.
0516-014 mirrorvg: []: The physical volume appears to belong to another
volume group.
0516-1200 mirrorvg: Failed to mirror the volume group.

I checked lspv and this showed the new disk as available:
$ lspv
hdisk0 none None
hdisk1 001016cc923411e7 rootvg active

However if I try to display the hdisk0 I get the following error:
$ lspv hdisk0
0516-304 : Unable to find device id hdisk0 in the Device
Configuration Database.

If I try to manually configure hdisk0 I get this message
$ cfgmgr -l hdisk0
cfgmgr: 0514-604 Cannot access the CuDv object class in the

Can anyone offer any suggestions as to what could be causing the problem?

Thanks
Gareth
