PDC-ISL-HP Unix从备份内核启动

当新生成的内核不能启动或新内核丢失时,HP Unix需要从备份内核启动。
如下所示:
1. 按[POWER]键开机。
2. 当提示10s之内按任意键盘中断时,按[ESC]键。
3. 系统进入PDC控制界面后,做如下操作:
   Main Menu> boot pri
   Interact with the IPL? y
4. 系统进入ISL控制界面。
5. 做如下操作:
   ISL> hpux -is /stand/vmunix.prev
   HP Unix将从原来的旧内核启动

Interacting with the PDC/BootROM
Interrupting the autoboot
menu choice: a        # some models go straight to BOOT_ADMIN
Useful PDC commands
 
BOOT_ADMIN> help # view help menu
BOOT_ADMIN> search # list all SCSI devices
BOOT_ADMIN> search ipl # list all possible boot devices
BOOT_ADMIN> path # list all boot paths in stable storage
BOOT_ADMIN> path pri scsi.6.0# set scsi.6.0 as primary boot path
BOOT_ADMIN> path alt scsi.0.0# set scsi.0.0 as alternate boot path
BOOT_ADMIN> boot alt # boot from the alternate boot path
BOOT_ADMIN> boot pri # boot from the primary boot path
BOOT_ADMIN> boot pri isl # boot from the primary to isl prompt
 
 
ISL‘s   hpux  工具
 
ISL>hpux [driver(hwpath;0)][kernelfile]                   (系统正常启动)    
ISL>hpux (0/0/1/0.2.0;0)/stand/vmunix
 
 
ISL>hpux ls [driver(hwpath;0)]/[path]                     (列出文件以寻找内核)
ISL>hpux -v                                               (列出hpux版本号)
ISL>hpux -m[p|s|x] driver(hwpath;0)kernelfile             (从镜像启动)
ISL>hpux -is [driver(hwpath;0)[kernelfile]                (进入单用户模式)
ISL>hpux -lm [driver(hwpath;0)[kernelfile]                (进入LVM维护模式)
ISL>hpux -lq [driver(hwpath;0)[kernelfile]                (不检查 LVM quorum启动)
 
where:
driver is device adapter driver (i.e. disc0, disc1, disc3, etc)
hwpath is appropriate harware path to boot device (i.e. 52.6.0, scsi.6.0, etc)
kernelfile is name of kernel  (i.e.  /stand/vmunix or  /stand/vmunix.prev)
path is directory path to specified file or directory (i.e. /stand)
