Volume ID Gone
Good Evening, I am hoping someone may have seen a simliar issue occur else where. Recently we experienced an issue where volume id on a 9980V disappeared and became unuseable to the operating system it was attached too. The first symptom of the problem occurred when IOS071I - missing channel and device end messages began being issued by the operating system. The volume was brought online to another system, and it showed that it had lost its volume identifier. The volume was clipped and further analysis showed that the VTOC and the data set (SYS1.HASPACE) was listed there. An attempt to bring the volume to the owner was unsucessful. There is no evidence of external access & activities being the cause of the volume identifier disappearing. The issue is under investigation from many sources. Thanks in advance.

Re: Volume ID Gone
Yes, observed something very similar once. The volume was not offline to all LPARs' when some volume level work was done. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of John Argall Sent: Tuesday, July 21, 2009 7:50 AM To: IBM-MAIN@bama.ua.edu Subject: Volume ID Gone Good Evening, I am hoping someone may have seen a simliar issue occur else where.

John, Is anyone experimenting with copy products (TrueCopy, FlashCopy, Shadowimage)?

Re: Volume ID Gone
Hi Ron, The box does have Truecopy Async running on it to a site about 1000km away. Our hardware vendor is still investigating, but has said a 'slot lock' is being seen in shared memory/cache generated by some internal task within the disk subsystem. Unfortunately, we have to play a wait and see game now as i am about all erep'd out, along with many other reports we've reviewed. regards, John. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
