Title: iscsi failure on select disks -- Post by: moon8dog on July 05, 2007, 08:12:44 PM Have a new iscsi array (jetstor) we just connected. Using the iscsi initiator (not the TOE).
There are 16 luns on the iscsi, all of them for a single AIX node. cfgmgr picks up every drive okay. Problem is with creating VGs... 0516-1182 /usr/sbin/mkvg Open Failure on hdisk4. 0516-862 /usr/sbin/mkvg: Unable to create volume group. lquerypv -h /dev/hdisk4 no return... This basic lquerypv should work just fine. Hit's all the other disks okay. The file /etc/iscsi/targets only has one line, using iscsi as the targets name, so it just picks up everything. Wanted to try and format/certify the drives, but diags doesn't list these drives... Any ideas? Title: Re: iscsi failure on select disks -- Post by: Michael on July 27, 2007, 12:45:15 PM My guess is that there are some additional files that need to be installed, in particular - updates to the Pd* (Predefined ODM Datafiles) so that AIX accesses the correct drivers. Continuing with my "guessing" the disks are standard enough to be recognized by AIX as a hdisk, but the generic AIX drivers are not working and/or need some customization. THE AIX Pd* includes all IBM supported devices and attempts to support non-IBM devices - but this is always dependent on mutual levels and understanding regarding protocol conformance.
Check with the supplier. And if it is IBM - do please comment - so I know my guesswork is off-track. Title: Re: iscsi failure on select disks -- Post by: rscotka on September 24, 2008, 10:04:37 PM What version of AIX are you using? There are issues
with different iscsi products on versions before 5.3 ML4......ML5 and above seems to make things lots easier.... |
