Hello, openSUSE experts, recently I have got unpleasant news from logs: end_device-0:10: mptsas: ioc0: removing sata device: fw_channel 0, fw_id 4, phy 3,sas_addr 0x922210b547a6049 [...] end_device-0:63: mptsas: ioc0: removing sata device: fw_channel 0, fw_id 4, phy 3,sas_addr 0x922210b547a6049 phy-0:3: mptsas: ioc0: delete phy 3, phy-obj (0xffff880272981c00) port-0:10: mptsas: ioc0: delete port 10, sas_addr (0x922210b547a6049) [...] port-0:63: mptsas: ioc0: delete port 63, sas_addr (0x922210b547a6049) audit: audit_backlog=326 > audit_backlog_limit=320 audit: audit_backlog=327 > audit_backlog_limit=320 audit: audit_lost=189 audit_rate_limit=0 audit_backlog_limit=320 [...] audit: audit_lost=423 audit_rate_limit=0 audit_backlog_limit=320 audit: backlog limit exceeded audit_log_start: 32 callbacks suppressed audit_log_start: 671 callbacks suppressed mptbase: ioc0: PhysDisk is now failed, out of sync mptbase: ioc0: PhysDisk is now missing, out of sync mptbase: ioc0: PhysDisk is now online, out of sync mptbase: ioc0: SMART data received, ASC/ASCQ = 5dh/10h mptbase: ioc0: volume is now degraded, enabled mptbase: ioc0: volume is now degraded, enabled, resync in progress mptbase: ioc0: RAID STATUS CHANGE for PhysDisk 0 id=4 mptbase: ioc0: RAID STATUS CHANGE for VolumeID 0 mptsas: ioc0: attaching sata device: fw_channel 0, fw_id 4, phy 3, sas_addr 0x922210b547a6049 scsi 0:0:11:0: Attached scsi generic sg3 type 0 scsi 0:0:11:0: Direct-Access ATA ST3500320NS SN05 PQ: 0 ANSI: 5 [...] scsi 0:0:64:0: Attached scsi generic sg3 type 0 scsi 0:0:64:0: Direct-Access ATA ST3500320NS SN05 PQ: 0 ANSI: 5 scsi target0:0:10: mptsas: ioc0: delete device: fw_channel 0, fw_id 4, phy 3, sas_addr 0x922210b547a6049 [...] scsi target0:0:63: mptsas: ioc0: delete device: fw_channel 0, fw_id 4, phy 3, sas_addr 0x922210b547a6049 Once, I had to hard reset it because of kernel panic during RAID syncing error. It is tower server IBM X3200 M3 with 4 x 500 GB hot-swap HDD http://www-03.ibm.com/systems/x/hardware/tower/x3200m3/ It serves as LAMP and SFTP. I used built-in SAS utility to create HW RAID 10 which openSUSE 12.2 sees as one disk. If it is important, it has UEFI, but I use legacy BIOS mode (and GRUB 1). I don't have so much experience with such HW, so I rather ask before taking action. It is still running. ;-) So am I correct, that one disc is dying? How to recognize which one? And can I really just open running machine the case, exchange HDD and wait little bit? ;-) Have a nice day, Vojtěch -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/
