Hi to all I have a supermicro server with LSI 3108 with - 2x300GB SAS spin drive in raid1 (virtual drive 0) - 2x300GB SAS spin drive in raid1 (virtual drive 1) - 2x200GB Intel SSD DC S3710 drives configured as JBOD in LSI bios In the IPMI storage health status eveything looks fine until I boot into Centos 7.1 (unfortunatelly I didn't try other OS, but also I'm not interested in other) After boot the status for the SSDs changing in ERROR The same thing happen when boot with the install CD Otherwise everything works fine. Is this hurt? Can I do something? Also I tried to install the latest LSI driver (06.809.18.00), but seems it is not loaded after restart: As the official driver install guide say, before the driver install, I installed the dkms from the epel repo. /var/log/messages: systemd-modules-load: Failed to find module 'override megaraid_sas 3.10.* weak-updates/megaraid_sas' /etc/modules-load.d/megaraid_sas.conf: override megaraid_sas 3.10.* weak-updates/megaraid_sas #modinfo megaraid_sas filename: /lib/modules/3.10.0-229.14.1.el7.x86_64/kernel/drivers/scsi/megaraid/megaraid_sas.ko description: LSI MegaRAID SAS Driver author: megaraidlinux at lsi.com version: 06.805.06.01-rh2 license: GPL rhelversion: 7.1 srcversion: C0124BBE9453A621D4086DB alias: pci:v00001000d0000005Fsv*sd*bc*sc*i* alias: pci:v00001000d0000005Dsv*sd*bc*sc*i* alias: pci:v00001000d0000002Fsv*sd*bc*sc*i* alias: pci:v00001000d0000005Bsv*sd*bc*sc*i* alias: pci:v00001028d00000015sv*sd*bc*sc*i* alias: pci:v00001000d00000413sv*sd*bc*sc*i* alias: pci:v00001000d00000071sv*sd*bc*sc*i* alias: pci:v00001000d00000073sv*sd*bc*sc*i* alias: pci:v00001000d00000079sv*sd*bc*sc*i* alias: pci:v00001000d00000078sv*sd*bc*sc*i* alias: pci:v00001000d0000007Csv*sd*bc*sc*i* alias: pci:v00001000d00000060sv*sd*bc*sc*i* alias: pci:v00001000d00000411sv*sd*bc*sc*i* depends: intree: Y vermagic: 3.10.0-229.14.1.el7.x86_64 SMP mod_unload modversions signer: CentOS Linux kernel signing key sig_key: E9:9F:C4:37:BD:9C:BF:B4:F1:B1:DA:87:C1:57:FF:66:56:9B:EE:66 sig_hashalgo: sha256 parm: lb_pending_cmds:Change raid-1 load balancing outstanding threshold.
