今天做了一次在小型机上升级HBA卡的微码的工作，在升级前，要检查小型机的HBA卡的型号，这个型号可以从小型机硬件配置文档里查找；其次，要确定当前HBA卡的版本，可以用如下的命令查看：--查看系统当前所有的HBA卡：test_db:/@root>#lsdev -C | grep fcsfcs0 Available 09-08 FC Adapterfcs1 Available 0E-08 FC Adapter--查看HBA卡微码的版本，注意lscfg命令的Z9字段，那里即为微码版本信息：test_db:/etc/microcode@root>#lscfg -vl fcs0fcs0 U5791.001.99200CK-P2-C01-T1 FC AdapterPart Number.................80P4543EC Level....................ASerial Number...............1F4400AF85Manufacturer................001FFeature Code/Marketing ID...280BFRU Number.................. 80P4544Device Specific.(ZM) (3)Network Address.............10000000C9402F8BROS Level and ID (02881914)Device Specific.(Z0)........1001206DDevice Specific.(Z1) (00000000)Device Specific.(Z2) (00000000)Device Specific.(Z3) (03000909)Device Specific.(Z4)........FF801315Device Specific.(Z5) (02881914)Device Specific.(Z6) (06831914)Device Specific.(Z7) (07831914)Device Specific.(Z8)........20000000C9402F8BDevice Specific.(Z9)........TS1.90A4 --微码版本信息，当前版本1.90A4Device Specific.(ZA)........T1D1.90A4Device Specific.(ZB)........T2D1.90A4Device Specific.(YL)........U5791.001.99200CK-P2-C01-T1test_db:/etc/microcode@root>#lscfg -vl fcs1fcs1 U5791.001.99200CK-P2-C05-T1 FC AdapterPart Number.................80P4543EC Level....................ASerial Number...............1F4530ABC9Manufacturer................001FFeature Code/Marketing ID...280BFRU Number.................. 80P4544Device Specific.(ZM) (3)Network Address.............10000000C94441F4ROS Level and ID (02881914)Device Specific.(Z0)........1001206DDevice Specific.(Z1) (00000000)Device Specific.(Z2) (00000000)Device Specific.(Z3) (03000909)Device Specific.(Z4)........FF801315Device Specific.(Z5) (02881914)Device Specific.(Z6) (06831914)Device Specific.(Z7) (07831914)Device Specific.(Z8)........20000000C94441F4Device Specific.(Z9)........TS1.90A4 --微码版本信息，当前版本1.90A4Device Specific.(ZA)........T1D1.90A4Device Specific.(ZB)........T2D1.90A4Device Specific.(YL)........U5791.001.99200CK-P2-C05-T1--做好这些准备工作之后，就可以解压从IBM下载的升级包，但下载时注意光纤卡的型号与微码版本--然后运用如下命令开始解压,在解压的过程中，会检查当前机器的型号是否满足要求：test_db:/tmp@root>#rpm -ihv --ignoreos pci.df1000fa-1-91A5.aix.noarch.rpm Checking machine typeMachine type IBM,9119-590 is ok,proceeding with installation.pci.df1000fa##################################################--解压完成后，会在/etc/microcode目录下生成一个文件df1000fa.191105(如果你升级到其它版本，文件名是不一样的)test_db:/etc/microcode@root>#ls -ltotal 13408-r--r--r-- 1 root system 20176 Jul 08 2004 cx_conc-r--r--r-- 1 root system 20768 Jul 08 2004 cx_e_conc-r--r--r-- 1 root system 28672 Jul 08 2004 cxpabios-r--r--r-- 1 root system 36864 Jul 08 2004 cxpafep-rwxr-xr-x 1 root system 664748 Jul 27 2006 df1000fa.191105 --新HBA 微码文件-r-xr-xr-x 1 bin bin 99995 Jun 17 2004 dgr0871014d.00.00-r-xr-xr-x 1 bin bin 197089 Jun 22 2004 dgr0b91014d.00.00-r-xr-xr-x 1 bin bin 267973 Jun 22 2004 dgr0c91014d.00.00-r-xr-xr-x 1 bin bin 316207 Jun 17 2004 dgr0d31014d.00.00-r-xr-xr-x 1 bin bin 99095 Jun 17 2004 dgr0f81014d.00.00-r--r--r-- 1 bin bin 74920 Jun 22 2004 ec8fd.00.03-r--r--r-- 1 root system 1071532 Nov 03 2004 ibmsis2780.img-r--r--r-- 1 root system 881312 May 26 2005 ibmsis5702.img-r--r--r-- 1 root system 1244888 May 26 2005 ibmsis5703.img-r--r--r-- 1 root system 1024068 Jun 17 2004 ibmsis5709.img-r--r--r-- 1 root system 881312 May 26 2005 ibmsis570B.img-r--r--r-- 1 root system 41472 Oct 12 2006 sxbios-r--r--r-- 1 root system 31232 Jun 17 2004 sxfep--在正式升级微码前，要确定当前系统在HBA卡上没有I0。
