Hi

any idea about this error ?

I've checked all XP device on local/remote are ok

Is this a BC or CA volume?

What is the output 0f 'pairdisplay -g vg01_02' ?

Remember that for BC volumes you must set the HORCC_MRCF env variable to 1 before proceeding:

export HORCC_MRCF=1
paircreate -g vg01_02 -d device28_M -vl

HORCC_MRCF is set to 1

Strange is that first I did command

paircreate -g vg01_02 -vg and got an error .
So I've repeated command specifyng first device device03_M .

After pairdisplay -g vg01_02 I've seen devices from 03 to 27 was in copy ; I was aspected only 03 in copy . At end all devices come in pair .

Local devices are also CA devices , that's primary BC devices. I'm tring making a secondary BC devices for backup purposes

Claudio -
A couple of things to note that we have encountered.
1. When adding new pairs to the horcm file, we normally stop and start the horcm to insure it reads the updated config.
(It appears you did so since the display works and they are in simplex mode.)
2. Insure the apporpriate horcminst is exported as well as the HOMRCF.
3. Not sure what our differences are but our normal create command goes like-
paircreate ???g ???groupname??? ???d P002S015 ???vl

Best of luck,

Regards,

Just noticed your comment on a second pair for backup purposes. In the horcm.conf file the column MU is for this purpose. a value of 0 or 1 may be used. 0=primary pair 1=backup pair in our shop. This is mandatory if the same primary is used with two different business copy devices.

Hang in there.

Problem solved running pvcreate for few devices at once . Seems raidmanager has a limit of pair can be created at same time.

I must say that my primary BC vols are also secondary CA vols .

Errate corrige .. I discover I can create a max of 8 pair using any devices ; while tring create next ( #9 ) pair i got the error. Seems a problem due license of BC that put a limit to Tera byte can be copied
