Re: diskinfo and ioscan not reporting
Don't use ioscan with -H option, this sometimes give vague results.
I know openning a case with HP for an issue where ioscan -fnH
It was learnt to use ioscan -fnC disk which produced more accurate results.
Check if you can find any disk error message in /var/adm/syslog/syslog.log and in EMS logs.
diskinfo will again report disk size 0byte, if there are issues with the Disk.
Thanks,
