Find the c#t#d# of the disk giving us problems by using the format command: # format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t0d0 <SUN4.2G cyl 3880 alt 2 hd 16 sec 135> /pci@1f,4000/scsi@3/sd@0,0 1. c0t1d0 <SUN4.2G cyl 3880 alt 2 hd 16 sec 135> /pci@1f,4000/scsi@3/sd@1,0 2. c2t0d0 <SUN4.2G cyl 3879 alt 2 hd 16 sec 135> <------ We will use this disk as an example /pci@6,4000/scsi@4/sd@0,0 3. c2t1d0 <SUN4.2G cyl 3879 alt 2 hd 16 sec 135> /pci@6,4000/scsi@4/sd@1,0 Specify disk (enter its number): --------------------------------------------------------------------------------------------------------------------------------
When we know the c#t#d# then use iostat -En to find the serial # of this disk # iostat -En c0t0d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAB3045S SUN4.2G Revision: 1705 Serial No: 9818M30787 Size: 4.29GB <4292075520 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c0t1d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAB3045S SUN4.2G Revision: 1705 Serial No: 9818M26895 Size: 4.29GB <4292075520 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c1t6d0 Soft Errors: 2 Hard Errors: 0 Transport Errors: 0 Vendor: TOSHIBA Product: XM5701TASUN12XCD Revision: 2395 Serial No: Size: 0.00GB <0 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 2 Predictive Failure Analysis: 0 c2t0d0 Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 Vendor: SEAGATE Product: ST34371W SUN4.2G Revision: 7462 Serial No: 9716E 30027 <---------- Serial # Size: 4.29GB <4290969600 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 1 Predictive Failure Analysis: 0 c2t1d0Soft Errors: 1 Hard Errors: 0 Transport Errors: 0 Vendor: QUANTUM Product: VK4550J SUN4.2G Revision: 8600 Serial No: 97146D4554 -------------------------------------------------------------------------------------------------------------------------------- From This serial number 9716E 30027 write down the last 5 numbers in this case it is 30027 On every disk in a Enterprise 450 there is a number on the front bracket in this example it is 0020772-9716E 30027 Notice that the last numbers match the serial number on the drive. Once you have a match you have found your disk! ___________________________________________________________________________________________ Notice: There are a few Seagate drives where the matching numbers are in the middle of the number given from iostat Example:c0t3d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: SEAGATE Product: ST34371W SUN4.2G Revision: 7462 Serial No: JDE 91535 0PJ46U The numbers 91535 match the numbers on the drive bracket for this disk.
