1、 检查系统运行模式：32位/64位：1.1、isalist v；isainfo v；isainfo b；64-bit mode#isalist -v sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc#isainfo -v64-bit sparcv9 applications32-bit sparc applications#isainfo b6432-bit mode#isalist -v sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7#isainfo -v32-bit sparc applications#isainfo b32注：A、 ISA：Industrial Standard Architecture，工业标准结构总线；B、 isainfo b用于查看内核位数C、 isalist的输出中，从高到底列出了CPU的指令状态，sparcv9+vis sparcv9是64位指令，sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7是32位的；D、 isainfo是用来识别当前系统支持的指令集的特征；-v参数：列出当前系统支持的应用程序的位数、采用的指令集结构；-b参数：列出当前系统的位数；1.2、32位和64为之间的转换方法：1.2.1、将64位转换为32位：方法一：A、isainfo b-查看当前的系统的位数；B、eeprom：查看当前的boot-file参数的设置：比如：bash-2.03# eeprom . boot-file: data not available. .C、使用eeprom boot-file=kernel/unix将目前的64位系统改为32位将Solaris的启动文件改为32位； bash-2.03# eeprom boot-file=kernel/unix 此命令没有输出，所以执行完之后，还需要使用eeprom |grep boot-file查看boot-file是否更改成功； bash-2.03# eeprom |grep boot-file boot-file=kernel/unixE、 重启：init 6；F、 确认是否修改成功：# isalistsparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc# isainfo -v32-bit sparc applications# isainfo -b32方法二：A、 进入OK模式：init 0； ok printenv boot-fileB、 在OK模式下：ok setenv boot-file kernel/unix;C、 ok boot；1.2.2、将32位转换64位：方法一：#eeprom boot-file=kernel/sparcv9/unix#init 6方法二：ok setenv boot-file kernel/sparcv9/unixok boot方法三：ok boot kernel/sparcv9/unix方法四：ok set-default boot-fileok boot2、 OK模式：OK模式下：ctrl+p显示前一个命令；ctrl+n-显示后一个命令；在OK模式下没有reboot命令ok模式下不能将命令使用“；”连用，比如不能使用sync；boot r2.1、banner：意为旗帜，标语的意识，放在此处用来列出有用的系统信息，包括机器model、内存的数量、HostID、MAC地址和boot prom版本： 2 ok bannerSun Enterprise 420R (2 X UltraSPARC-II 450MHz), No KeyboardOpenBoot 3.23, 1024 MB memory installed, Serial #15726982.Ethernet address 8:0:20:ef:f9:86, Host ID: 80eff986.2.2、printenv：此命令可以列出所有NVRAM中的参数：分三列：参数的名字，当前的设置，默认的参数设置2 ok printenvVariable Name Value Default Valuescsi-initiator-id 7 7keyboard-click? false falsekeymap ttyb-rts-dtr-off false falsettyb-ignore-cd true truettya-rts-dtr-off false falsettya-ignore-cd true truettyb-mode 9600,8,n,1,- 9600,8,n,1,-ttya-mode 9600,8,n,1,- 9600,8,n,1,-pcia-probe-list 1,2 1pcib-probe-list 1,3,2,4,5 1,3,2,4,5.注意：printenv也可以用来显示一个单独的参数的数值，比如：2 ok printenv auto-boot?auto-boot? = trueNVRAM参数的命令规律：凡是结果为布尔值（0或1、true或false）的参数，均以？结尾；2.3、setenv：setenv命令用于改变在NVRAM中某个参数的当前值：2 ok setenv auto-boot? falseauto-boot? = false2.4、reset-all：此命令用于复位系统，清除所有缓冲和系统寄存器：如果auto-boot？参数的值是true，则执行reset-all命令之后，会重新启动系统；如果auto-boot？参数的值是false，则执行reset-all命令之后，会返回到ok模式； 2 ok reset-allResetting .

False（2）、reset-all： ok reset-all2.7.1、probe-ide： Probe-ide用来识别集成在主板上的IDE控制器上连接的外围设备； 注意：这个命令不能显示目标地址，只能显示设备号；2.7.2、probe-scsi： Probe-SCSI用来识别集成在主板上的scsi控制器上连接的外围设备； probe-scsi-all：用于寻找所有集成在主板上的SCSI控制器上连接的外围设备和所有绑定到Sbus或者PCI SCSI控制器上的外围设备，包括FC设备； 1 ok probe-scsi-all/pci1f,4000/scsi3,1/pci1f,4000/scsi3Target 0 Unit 0 Disk SEAGATE ST39204LCSUN9.0G4207Target 1 Unit 0 Disk SEAGATE ST318404LSUN18G 4207Target 6 Unit 0 Removable Read Only device TOSHIBA XM6201TASUN32XCD1103 2.8、sync命令： 如果一个挂起的系统，使用正常的Solaris命令无法得到任何响应，则可以强行进入ok模式，然后使用sync尝试保存还没有写回磁盘的数据，此时系统会产生一个core文件，core文件完成后，系统会重新启动；如果你不想保存core文件，在看到syncing file systems时，可以强行中断；2 ok syncpaniccpu2/thread=2a10015dd20: sync initiatedsched: software trap 0x7fpid=0, pc=0xf00515d8, sp=0x2a10015cf01, tstate=0x8800001400, context=0x0g1-g7: 1003aa9c, 10418400, 10418400, 0, 0, 0, 2a10015dd2000000000fff83d00 unix:sync_handler+150 (1041b098, 10000000, 1041c8b8, 104241a0, 16, 0) %l0-3: 00000300010c8018 0000000001474d38 0000000000000010 000003000165dc00 %l4-7: 00000000004a6000 000003000167b698 0000000000000002 000000000000000100000000fff83de0 unix:vx_handler+8c (f0000000, 10418580, 10418478, fff4d5a8, f003acd5, 0) %l0-3: 00000000100290dc 0000000000000000 0000000000000000 000002a1000e5d20 %l4-7: 000002a1000d2000 0000000000000003 00000300000687b0 000002a100157d5000000000fff83e90 unix:callback_handler+20 (fff4d5a8, fffda280, 0, 0, 0, 0) %l0-3: 0000000000000016 00000000fff83741 00000000f0000000 00000000fffe0000 %l4-7: 00000000f0051584 0000000000000000 0000000000000000 00000000fffeefa0syncing file systems. 1 1 donedumping to /dev/dsk/c0t0d0s1, offset 429850624100% done: 8554 pages dumped, compression ratio 6.80, dump succeededrebooting.Resetting .
