HP Proliant Microserver Gen8 :boot logical drive is configured but is missing or offline

[topsoft]

Everything on the original server was normal. It was equipped with 4 hard drives and all were equipped with disk arrays. After removing the hard drive and replacing it with a new hard drive, the situation changed. What should I do?

Neither F5 nor F10 can enter the relevant settings page, and both are automatically reloaded.

Hello,

From the images provided by the first and second links, I understand that there is no longer any logical volume present.

Also, the post mentions "removing the hard drive and replacing it with a new hard drive, the situation changed".

• Based on the above statements, I believe that the logical volume failed because the drive that was removed for replacement might have been good and that this act of removing broke the RAID array. To expand on it, what I meant was that already a drive is defective in the RAID array, but it is intact due to the fault tolerance, but if another drive in the array were to fail the fault tolerance is breached and the data is lost.
• As there is no logical array, it would be recommended to run the Array Configuration Utility (ACU), determine if all drives are good and then rebuild the array and restore data from valid back up.

If you believe that only the defective hard drive was replaced then it would be recommended to clear the server's NVRAM. To do so, you may perform the following:

• Power off the server and remove the power cable from the power supply.
• Remove the access panel.
• You may refer to item No. 15, of the diagram "System board components", on page 9 of the HP ProLiant MicroServer Gen8's User Guide for the location of the System Maintenance Switch.
• Once identified, set switch 'S6' from its defautl position 'Off' to 'On'
• Replace the access panel, connect the power cable to the power supply and power on the server.
• When the display indicates that the  one of the system maintenance switch is turned on and needs to be reversed, power off the server and reverse the steps mentioned above and power on the server.

@TVVJ ILO Overview System Health shows Degraded. I've tried the method mentioned in this link (https://support.hpe.com/hpesc/public/docDisplay?docId=a00048622en_us), but it still doesn't work. Do I have to replace the motherboard?

Hello,

The referred customer advisory would help to format the iLO's NAND flash. iLO is out of bandwith for management, meaning self contained, independant circuitry to help manage the server. Hence, the format of iLO is not going to make changes to any of the server's circuitry.

You may review the previous reply and if found appropriate, attempt them and see if it helps.
