Ken/Scott, On FreeBSD11.0 RC1, we are facing an issue where SATA drives connected behind LSI's MegaRAID controller getting deleted and added back after controller reset. I am using Broadcom/Avago/LSI's MegaRAID Invader controller(device ID- 0x005d). The point to note here is- this behavior is not observed with SAS drives on FreeBSD11.0-RC1. Also on FreeBSD10.3 this behavior is not at all observed on SATA as well. We are debugging the issue but it would be much helpful if we can get quick inputs/pointers. Please find below the detailed information- OS: FreeBSD 11.0 RC1 Controller: LSI's MegaRAID invader controller Connected devices list: root@freeBSD11:~ # camcontrol devlist <ST500NM0011 PA09> at scbus5 target 0 lun 0 (pass0,ada0) <AHCI SGPIO Enclosure 1.00 0001> at scbus6 target 0 lun 0 (ses0,pass1) <ATA ST9250610NS SN01> at scbus8 target 51 lun 0 (da9,pass11)----------------------------------------->this is SATA drive which is getting deleted and re-added post controller reset <SEAGATE ST9300605SS 0004> at scbus8 target 163 lun 0 (da8,pass10) <LSI Default 5.00> at scbus9 target 0 lun 0 (da6,pass8) <LSI Default 5.00> at scbus9 target 1 lun 0 (da2,pass4) <LSI Default 5.00> at scbus9 target 2 lun 0 (da0,pass2) <LSI Default 5.00> at scbus9 target 3 lun 0 (da7,pass9) <LSI Default 5.00> at scbus9 target 4 lun 0 (da3,pass5) <LSI Default 5.00> at scbus9 target 5 lun 0 (da1,pass3) <SEAGATE ST600MP0005 VS09> at scbus10 target 48 lun 0 (da4,pass6) <SEAGATE ST600MP0005 VS09> at scbus10 target 54 lun 0 (da5,pass7) Relevant dmesg logs snippet(da9 is SATA drive which is getting deleted and added back): ================================ mrsas0: Initiaiting OCR because of FW fault! mrsas0: Waiting for FW to come to ready state mrsas0: Jbod map is supported mrsas0: Reset successful da9 at mrsas0 bus 1 scbus8 target 51 lun 0 da9: <ATA ST9250610NS SN01> s/n 9XE02AR2 detached (da9:mrsas0:1:51:0): Periph destroyed (da9:mrsas0:1:51:0): UNMAPPED (da9:mrsas0:1:51:0): fatal error, could not acquire reference count g_access(918): provider da9 has error g_access(918): provider da9 has error g_access(918): provider da9 has error (da9:mrsas0:1:51:0): UNMAPPED da9 at mrsas0 bus 1 scbus8 target 51 lun 0 da9: <ATA ST9250610NS SN01> Fixed Direct Access SPC-4 SCSI device da9: Serial Number 9XE02AR2 da9: 150.000MB/s transfers da9: 238475MB (488397168 512 byte sectors) ================================= Thanks, Sumit
