SAN Boot Disk goes offline after reboot
I am unable to install the server 2016 image on the SAN boot disk due to a recurrent disk offline issue.
Hardware : Proliant DL380 Gen 9 with StoreFabric CN1100R Dual Port card
Storage Model : 3par 8400
We have the same storage working fine on 3 other servers
The disk goes into offline mode after each reboot.
Troubleshooting done
- Change the boot policy from offline to san policy=OnlineAll
- attributes disk clear readonly on disk 0
- Online the disk yet after reboot the disk goes to offline mode.

Hi Shiva,
I have done this and not solving the issue. The disk will go offline after reboot once I have done this.

Re: SAN Boot Disk goes offline after reboot
I'm encountering the same issue with my SAN boot disk going offline after reboot. I'm also using a Proliant DL380 Gen 9 with a StoreFabric CN1100R Dual Port card and a 3par 8400 storage model. It's frustrating to see the disk consistently going offline despite troubleshooting steps like changing the capcut pro apk boot policy and clearing readonly attributes. It's perplexing especially considering that the same storage setup is working fine on three other servers. If anyone has insights or suggestions on how to resolve this, I'd greatly appreciate it.

Re: SAN Boot Disk goes offline after reboot
could be related to the FC HBA. There are known issues with certain HBA cards where only one port is displayed in the one-time boot menu, which could potentially cause issues with SAN boot configurations. You may want to check if your StoreFabric CN1100R Dual Port card is affected by this issue. If it is, you might need to adjust your network boot setup for the affected FC HBAs. see this advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=a00134530en_us&docLocale=en_US

Re: SAN Boot Disk goes offline after reboot
Seems that this issue only affects Proliant Gen10 servers. Nevertheless, I have checked on Gen9 server and it shows empty without any card but I know for sure that the card is connected and the disk is available for use. Same situation on 3 more servers where I don't see the card under PCIe Slot network boot but the disk is working as expected.

Re: SAN Boot Disk goes offline after reboot
Fankly, I am out of ideas then. one random guess FWIW... https://support.hpe.com/hpesc/public/docDisplay?docId=sd00003169en_us&page=GUID-24894714-B928-4068-8B34-F1DA7F606A00.html&docLocale=en_US says "If Manage boot settings is disabled, HPE OneView does not change the PXE boot mode or PXE boot policy."
