SAN Boot Disk goes offline after reboot

Pubalan-Shell — Tue, 02 Apr 2024 03:55:01 GMT

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 @Pubalan-Shell,

Along with making SAN online, I got the detail to make disk online. Here it is-

1) Run the diskpart utility by running the command:

diskpart.exe

2) To display the SAN policy, run the command:

diskpart> sanSAN Policy: Offline Shared

3) Change the SAN policy to be online with the command:

diskpart> san policy=OnlineAllDiskpart successfully changed the SAN policy for the current operating system.

4) To get summary information about each disk, run the command:

diskpart>list diskDisk Status Size Free Dyn Gpt--------------- ------------------ ----------- ----------Disk 0 Online 40 GB 0 B*Disk 1 Offline 60 GB 1024 KB

5) Select Disk 1 (currently offline disk) with the command:

diskpart>select disk 1Disk 1 is now the selected disk

6) Clear the read-only attribute for Disk 1 with the command:

diskpart>attributes disk clear readonlydisk attributes cleared successfullydiskpart>attributes diskcurrent read-only state: noboot disk: nopagefile disk: nohibernation file disk: nocrashdump disk: noclustered disk: no

7) Bring Disk 1 online with the command:

diskpart>online diskdiskpart successfully onlined the selected disk

Hi Shiva,

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

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

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.

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."
