Inconsistent disk (4287722)

Warning!
This knowledge article applies to the following unsupported hardware appliances:

• SCB N5000
• SCB N10000
• SSB N5000
• SSB N10000
  

The array is sending an alert about an inconsistent disk on appliances which have hardware RAID controller.

Sample email alert:

DISMAN-EVENT-MIB::sysUpTimeInstance 184299881
    SNMPv2-MIB::snmpTrapOID.0 XCB-SNMP-MIB::xcbRaidStatus
    XCB-SNMP-MIB::description Raid status changed; old_status='Optimal', status='Degraded', failed=''

The following command can also show such disks in the boot shell:

arcconf getconfig 1 ld|grep 'Inconsistent'

You need to re-initialize the disk and push back the array using these commands in the boot shell of the appliance:

1. arcconf failover 1 on
   

2. arcconf rescan 1
   

3. arcconf task start 1 device 0 DISK_ID initialize
   

4. arcconf task start 1 device 0 DISK_ID verify_fix
   

5. arcconf setstate 1 device 0 DISK_ID RDY
   

6. arcconf setstate 1 device 0 DISK_ID HSP logicaldrive 0
   

7. After the rebuild finished, check the array:

arcconf task start 1 logicaldrive 0 verify_fix

The value of DISK_ID can be found using this one-liner script in the boot shell:

for LINE in $(arcconf getconfig 1 ld|awk '/Inconsistent/ {print $8"\n"}');do arcconf getconfig 1 pd|grep -B6 $LINE|awk -F'[ :,()]*' '/Serial/ {SERIALNUM=$3}; /Channel,Device/ {IDNUM=$8}; END {print "Disk Serial: "SERIALNUM" -- Disk ID: "IDNUM}';done

This prints the disk's serial number and the DISK_ID for the previous commands.

If it prints three or more disks, please open a Support Ticket immediately as it may mean data loss!
