Hi, I get these below information. Please help me understand about "SMART Health Status: FAILURE PREDICTION THRESHOLD EXCEEDED: ascq=0x5 [asc=5d, ascq=5]" and what does that error mean. Does it mean that the SAS disk 0 is failing and has serious issues and needs to be replaced and also do i need to run health status test with different options/flags or switches. /usr/sbin/smartctl -d megaraid,0 -a /dev/sda smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-308.1.1.el5] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Vendor: SEAGATE Product: ST3300657SS Revision: ES65 User Capacity: 300,000,000,000 bytes [300 GB] Logical block size: 512 bytes Logical Unit id: 0x5000c500477d63bb Serial number: 6SJ46RZB Device type: disk Transport protocol: SAS Local Time is: Fri Jul 27 06:50:49 2012 IST Device supports SMART and is Enabled Temperature Warning Disabled or Not Supported SMART Health Status: FAILURE PREDICTION THRESHOLD EXCEEDED: ascq=0x5 [asc=5d, ascq=5] Current Drive Temperature: 33 C Drive Trip Temperature: 68 C Elements in grown defect list: 2048 Vendor (Seagate) cache information Blocks sent to initiator = 2518358542 Blocks received from initiator = 3507177513 Blocks read from cache and sent to initiator = 19620730 Number of read and write commands whose size <= segment size = 35772014 Number of read and write commands whose size > segment size = 103 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3903.10 number of minutes until next internal SMART test = 32 Error counter log: Errors Corrected by Total Correction Gigabytes Total ECC rereads/ errors algorithm processed uncorrected fast | delayed rewrites corrected invocations [10^9 bytes] errors read: 7599922 9416 0 7609338 7609338 360.930 0 write: 0 0 0 0 0 1851.172 0 verify: 96309427 1108629 0 97418056 97419201 62032.969 3455 Non-medium error count: 3 SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background long Completed 32 1 - [- - -] # 2 Background short Completed 32 1 - [- - -] Long (extended) Self Test duration: 3200 seconds [53.3 minutes] [root@~]# /usr/sbin/smartctl -d megaraid,1 -a /dev/sda smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-308.1.1.el5] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Vendor: SEAGATE Product: ST3300657SS Revision: ES65 User Capacity: 300,000,000,000 bytes [300 GB] Logical block size: 512 bytes Logical Unit id: 0x5000c500477d49fb Serial number: 6SJ44JEH Device type: disk Transport protocol: SAS Local Time is: Fri Jul 27 06:50:55 2012 IST Device supports SMART and is Enabled Temperature Warning Disabled or Not Supported SMART Health Status: OK Current Drive Temperature: 32 C Drive Trip Temperature: 68 C Elements in grown defect list: 0 Vendor (Seagate) cache information Blocks sent to initiator = 1288378070 Blocks received from initiator = 3519302272 Blocks read from cache and sent to initiator = 19977846 Number of read and write commands whose size <= segment size = 35969964 Number of read and write commands whose size > segment size = 102 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3903.00 number of minutes until next internal SMART test = 32 Error counter log: Errors Corrected by Total Correction Gigabytes Total ECC rereads/ errors algorithm processed uncorrected fast | delayed rewrites corrected invocations [10^9 bytes] errors read: 16718097 0 0 16718097 16718097 352.119 0 write: 0 0 0 0 0 1810.643 0 verify: 197332427 0 0 197332427 197332427 5156.549 0 Non-medium error count: 0 SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background long Completed 32 1 - [- - -] # 2 Background short Completed 32 1 - [- - -] Long (extended) Self Test duration: 3200 seconds [53.3 minutes] Regards Kaushal _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
