Operating Systems Solaris Sun Fire v440 Hard disk or controller broken? WARNING: /pci@1f,700000/scsi@2/sd@0,0 (sd1) Post 303044055 by hicksd8 on Thursday 13th of February 2020 05:15:54 AM

The Raid controller is not showing no problems, as you put it.

RESYNCING means that the controller is remirroring the Raid1 disks because of a problem. Depending on the capacity of the Raid1 disks (they will typically be exactly the same size) this resyncing shouldn't take very long, however, whilst this is in progress, system response time will be impacted. Once complete, the status should become OPTIMAL.

If the resyncing is falling over for some reason then the process might be restarting over and over and OPTIMAL is never achieved. What for that. If that is the case I would be inclined to first if possible take the system down and re-seat all SCSI/SATA cables both ends (disk and mobo) and all disk power supply plugs. Reboot and see if the problem persists. If it does, then most likely one of the disks is faulty. It's possible but unlikely that the raid controller is faulty. All the moving parts are the disks.

You could remove the faulty raid1 drive (the one continuously resyncing) and put it on another machine running diagnostics. Perhaps completely reformat and try again. Otherwise, it's a new disk required.

NAME

       mega_sas - SCSI HBA driver for LSI MegaRAID SAS controller

DESCRIPTION

       The mega_sas MegaRAID controller host bus adapter driver  is a  SCSA-compliant  nexus  driver that supports the Dell PERC 5/E, 5/i, 6/E and
       6/i RAID controllers, the IBM ServeRAID-MR10k SAS/SATA  controller and  the  LSI  MegaRAID  SAS/SATA  8308ELP,  8344ELP,  84016E,  8408ELP,
       8480ELP, 8704ELP, 8704EM2, 8708ELP, 8708EM2, 8880EM2 and 8888ELP series of controllers.

       Supported  RAID	features  include RAID levels 0, 1, 5, and 6, RAID spans 10, 50 and 60, online capacity expansion (OCE), online RAID level
       migration (RLM), auto resume after loss of  system power during arrays, array rebuild or reconstruction (RLM) and configurable stripe  size
       up  to  1MB. Additional supported RAID features include check consistency for background data integrity, patrol read for media scanning and
       repairing, 64 logical drive support, up to 64TB LUN support, automatic rebuild and global and dedicated hot spare support.

CONFIGURATION

       The mega_sas.conf file contains no user configurable parameters. Please configure your hardware through the related  BIOS  utility  or  the
       MegaCli	configuration  utility.  If  you  want to install to a drive attached to a mega_sas HBA, you should create the virtual drive first
       from the BIOS before running the Solaris install. You can obtain the MegaCli utility from the LSI website.

       The mega_sas device can support up to  64 virtual disks. Note that BIOS numbers the virtual disks as 1 through 64, however in  the  Solaris
       operating  environment virtual disks are numbered from 0 to 63.	Also note that SAS and SATA drives cannot be configured into the same vir-
       tual disk.

KNOWN PROBLEMS AND LIMITATIONS

       The mega_sas driver does not support the LSI MegaRAID SAS 8204ELP, 8204XLP, 8208ELP, and 8208XLP controllers.
