Drives at these levels must first be updated to C504(C544,9GB), and then to this latest level. Contact IBM service representative to obtain microcode level C504(C544 for 9GB). *4.0 Determine the Drive Model, FRU&PN and Current Microcode level:* *a- SCSI Drives attached to SCSI Controllers(Non RAID)* To see the drive type and current microcode level, Execute the following command: lscfg -vl hdisk* |pg Example of the info on a 18.2GB SCSI hard disk: lscfg -vl hdisk1 DEVICE LOCATION DESCRIPTION hdisk1 10-68-00-13,0 16 Bit LVD SCSI Disk Drive (18200MB) Manufacturer................IBM Machine Type and Model......ST318305LW FRU Number..................09P4429 ROS Level and ID............43353046 Serial Number...............3JK0031Q EC Level....................0H11333 Part Number.................09P4428 Device Specific.(Z0)........000003129F00013E Device Specific.(Z1)........1109C50F Device Specific.(Z2)........1000 Device Specific.(Z3)........01309 Device Specific.(Z4)........0001 Device Specific.(Z5)........22 Device Specific.(Z6)........162870 C If the data returned in the "Part Number" field matches the one listed above AND the "ROS Level and ID...." field of that data is "43353046" or below [(43353446 or below for 9.1GB drives)], this microcode applies. If this level is already installed then the "ROS Level and ID...." shows: "43353046" ["43353446" for 9.1GB drive)]. *Note*: Drive microcode level is displayed in Hex value of ASCII characters in VPD data. Each alpha-numeric ASCII character converts to a 2-digit hex number. For example in VPD displayed above, 43 Hex= ASCII character C; 35 Hex= ASCII character 5 ; 30 Hex=ASCII character 0; 46 Hex=ASCII character "F", therefore the microcode level is C50F. Also note that last four digits of field "Device Specific.(Z1)........1109*_C50F_*" shows drive's microcode level. For SP systems with multiple nodes, you can use the following command to query all of the nodes at one time. Use of this command will also limit the amount of data returned, making it easier to audit. It returns only the pertinent information: node name, hdisk number, ROS Level and ID and part number. dsh -a lscfg -v |egrep 'hdisk|ROS|Part' pesp_n1: hdisk0 10-60-00-0,0 16 Bit LVD SCSI Disk Drive (18200MB) pesp_n1: ROS Level and ID............43353046 pesp_n1: Part Number.................09P4428 pesp_n5: hdisk0 10-60-00-0,0 16 Bit LVD SCSI Disk Drive (18200MB) pesp_n5: ROS Level and ID............43353046 pesp_n5: Part Number.................09P4428 pesp_n5: hdisk1 10-60-00-8,0 16 Bit LVD SCSI Disk Drive (18200MB) pesp_n5: ROS Level and ID............43353046 pesp_n5: Part Number.................09P4428 *b- SCSI Drives attached to SCSI RAID Controllers* At AIX command line, type: Diag Select "Task Selection" from diagnostics menu.
