First of all some information about the environment (it's from our customer):
-
AIX 5.2
-
EMC Symmetrix (attached via FC SAN)
-
HP MSA 1000 (attached via FC SAN)
Cause the old Symmetrix went End of Service Life, we want do do a migration of the data on it.
So the customer created some disk space for the AIX-server and we made the SAN-zoning.
After the "cfgmgr" command we could see the new disks "hdisk25" and "hdisk26".
root@oradb1:/ > lsdev -Cc disk
...
hdisk25 Available 0A-08-02 Other FC SCSI Disk Drive
hdisk26 Available 0A-08-02 Other FC SCSI Disk Drive
We also saw the attributes from the disks:
root@oradb1:/ > lscfg -vl hdisk25
hdisk25 U787B.001.DNW4959-P1-C2-T1-W500508B30090A1C9-L2000000000000 Other FC SCSI Disk Drive

But wen we created the volume group we get this error:
0516-1182 /usr/sbin/mkvg Open Failure on hdisk25.
0516-862 /usr/sbin/mkvg: Unable to create volume group.
Has someone an idea what we made wrong?
