7 Troubleshooting your system To get help with your Dell PowerEdge RAID Controller (PERC) S160, you can contact your Dell Technical Service representative or see https://www.dell.com/support. Topics: • Precautions for hot removal or hot insertion of NVMe drives • Unable to configure Linux RAID using UEFI Configuration Utility • Performance degradation after disabling SATA physical disk write cache policy • Unable to modify any feature settings in UEFI or OPROM • Extra reboot during OS installation • OS installation failing on NVMe PCIe SSD with third-party driver • Server performance is slow and crashes during OS installation on the SATA configuration • Server performance is slow during OS installation on the NVMe configuration • System startup issues • The BIOS configuration utility option does not display • Configuring RAID using the ROM utility option is disabled • Warning Messages • Other errors appearing on the BIOS screen • Physical disk - related errors • Virtual disks - related errors • S160 config driver is not installed after S160 DUP is run • S160 driver not identifying P4800 drives Precautions for hot removal or hot insertion of NVMe drives Corrective Action: If you are performing multiple hot-plug operations a minimum of 30 seconds is required before performing any hot removal or hot insertion operation, and Open manage storage services (OMSS) should reflect each performed hot removal or hot insertion operation before performing the next hot removal or hotinsertion. NOTE: Not maintaining a time interval of 30 seconds between two consecutive hot-plug operations may result in an undefined behavior. Unable to configure Linux RAID using UEFI Configuration Utility Likely Cause: Corrective Action: Option to select Linux RAID in Configuring Linux RAID page will be disabled if RAID is already configured. To resolve this issue: 1. If applicable, delete the virtual disk created in Windows RAID. 2. Convert physical disk to Non-RAID disk. See Converting physical disk to Non-RAID disk. 3. Convert physical disk to RAID. See Converting physical disk to RAID capable disk. 4. Configure Linux RAID. See Configuring Linux RAID 36 Troubleshooting your system
