Applies to:  

BNS Platform Hardware - Version HLRR 4.0 and later
Information in this document applies to any platform.



Goal


To understand, and attempt to avoid a Disaster Recovery (DR) of a T1200 HLRR 4.1 server because the following syscheck disk failure. 


* meta: FAILURE:: MAJOR::3000000000000002 -- Server Internal Disk Error
* meta: FAILURE:: md status check failed.


Solution


 


*****Update: Procedural Resolution Found. Please see updated procedure (DiskDrive_Replacement_on_a_T1200_EXHR_server_v3.pdf)*****


 


 If 'syscheck' and 'alarmMgr' return the following errors. Please open a SR and request the Oracle DSR TAC engineer to open an internal case with Platform Engineering/TPD.


 




$ sudo syscheck -v disk all
Running modules in class disk...
* meta: FAILURE:: MAJOR::3000000000000002 -- Server Internal Disk Error
* meta: FAILURE:: md status check failed.
One or more module in class "disk" FAILED


$ alarmMgr --alarmStatus
SEQ: 38 UPTIME: 2758008 BIRTH: 1512284477 TYPE: SET ALARM: TKSPLATMA2|tpdIntDiskError|1.3.6.1.4.1.323.5.3.18.3.1.2.2|32301|Equipment|Equipment Malfunction|HOST-RESOURCES-MIB::hrStorageDescr:1.3.6.1.2.1.25.2.3.1.3:OCTET_STRING:<undef>




A strange behavior, and failure, has been observed during a replacement of a hard-drive, specifically during the 'cpDiskCfg' command. This failure has forced a Disaster Recovery (DR) of the T1200 server.


# /usr/TKLC/plat/sbin/cpDiskCfg
/proc/scsi/scsi shows a device on 0:0:0:0
/proc/scsi/scsi shows a device on 2:0:1:0
/proc/scsi/scsi shows a device on 2:0:2:0
/proc/scsi/scsi shows a device on 2:0:3:0
probing for 'sdc' on SCSI 6:0:2:0
ERROR: could not open /sys/class/scsi_host/host6/scan for writing, No such file or directory


  A troubleshooting session with TPD engineering should be done prior to taking any actions or replacing the hard-drive. If possible, an alternative to a DR should be found.


Collect the savelogs_plat:




$ sudo /usr/TKLC/plat/sbin/savelogs_plat --workdir=/var/TKLC/db/filemgmt


or if the T1200 server reporting the alarm is a NOAM server use:


$ sudo /usr/TKLC/plat/sbin/savelogs_plat --disable-test=resolv --workdir=/var/TKLC/db/filemgmt
