Probably you could ask Storage guys if they see something at SAN side at that specific time and if it is re-occuring then monitoring closely LPAR and VIO could maybe reveal some peak/hiccup at CPU/Memory/IO side.aixhttps://www.blogger.com/profile/11198511213080760662noreply@blogger.comtag:blogger.com,1999:blog-5391325129965939458.post-88132202262790783972020-06-06T01:31:03.298+02:002020-06-06T01:31:03.298+02:00Hi,

I replaced the adapter (by just removing the adapter and put new one from stock) and noticed same WWPN allocated to all LPARS, and since my LPARs boot from LUNs all booted properly. <br /><br />My question is - WWPN should change after HBA card replcement? or since HMC generate it through hypervisor, nothing should be changed?
