Booting issues & Problems in Solaris : FkHLinux联盟
FkHLinux联盟
Following are some of the booting issues ,error messages their meaning and possible solutions FkHLinux联盟
FkHLinux联盟
1) Booting in single user mode and mounting root disk . FkHLinux联盟
2) Making boot device alias FkHLinux联盟
3) "Timeout waiting for ARP/RARP packet"? error message. FkHLinux联盟
4) "The file just loaded does not appear to be executable" error message. FkHLinux联盟
5) "bootblk: can't find the boot program" error message. FkHLinux联盟
6) "boot: cannot open kernel/unix" error message . FkHLinux联盟
7) "Error reading ELF header"? error message . FkHLinux联盟
8) "Cannot open '/etc/path_to_inst'" error message. FkHLinux联盟
9) "Can't stat /dev/rdsk/c0t3d0s0" error message . FkHLinux联盟
FkHLinux联盟
1.Booting in single user mode and mounting root hard disk. FkHLinux联盟
Most important step in diagnosing the booting problems is booting the system in single user mode and examining the hard disk for possible errors & work out the corrective measure. Single user mode can be achieved by any of the following methods :- FkHLinux联盟
ok>; boot -s ;from root disk FkHLinux联盟
ok>; boot net -s ;from network FkHLinux联盟
FkHLinux联盟
ok>;boot cdrom -s ;from cdrom FkHLinux联盟
Rebooting with command: cdrom -s FkHLinux联盟
Configuring the /devices directory FkHLinux联盟
Configuring the /dev directory | FkHLinux联盟
INIT: SINGLE USER MODE FkHLinux联盟
# FkHLinux联盟
# fsck /dev/rdsk/c0t3d0s0 FkHLinux联盟
# mount /dev/dsk/c0t3d0s0 /mnt FkHLinux联盟
FkHLinux联盟
Perform the required operation on mounted disk , now accessible through /mnt ,& unmount the hard disk after you are done ; FkHLinux联盟
# umount /mnt FkHLinux联盟
# reboot FkHLinux联盟
FkHLinux联盟
2.Making boot device alias FkHLinux联盟
In case system can not boot from primary disk and it is needed to make another boot disk to access the data , nvalias command is used . FkHLinux联盟
nvalias command makes the device alias and assigns an alternate name to a physical disk. Physical address of target disk is required which can be had by show-disk command on ok>;. FkHLinux联盟
FkHLinux联盟
ok>; nvalias disk7 /iommu@f,e0000000/sbus@f,e0001000/dma@3,81000/esp@3,80000/sd2,0 FkHLinux联盟
The new aliased disk can be named as boot disk or can be used for booting by refering its name . FkHLinux联盟
ok>; setenv boot-device disk7 FkHLinux联盟
ok>;reset FkHLinux联盟
or FkHLinux联盟
ok>; boot disk7 FkHLinux联盟
FkHLinux联盟
3."Timeout waiting for ARP/RARP packet"? FkHLinux联盟
At ok>; type printenv and look for these parameters . FkHLinux联盟
boot-device disk FkHLinux联盟
mfg-switch? false FkHLinux联盟
diag-switch? false FkHLinux联盟
if you see "boot-device net " or true value for the other two parameter change it to the values above. FkHLinux联盟
In case you wants to boot from network make sure your client is properly configured in boot server and network connections & configuration are proper. FkHLinux联盟
FkHLinux联盟
4."The file just loaded does not appear to be executable." FkHLinux联盟
Boot block on the hard disk is corrupted .Boot the system in single user mode with cdrom and reinstall boot block . FkHLinux联盟
#installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t3d0s0 FkHLinux联盟
FkHLinux联盟
5."bootblk: can't find the boot program" FkHLinux联盟
boot block can not find the boot programe - ufsboot in Solaris .Either ufsboot is missing or corrupted . In such cases it can be restored from the cdrom after booting from cdrom & mounting the hard disk FkHLinux联盟
# cp /platform/`uname -i`/ufsboot /mnt/platform/`uname -i` FkHLinux联盟
FkHLinux联盟
6."boot: cannot open kernel/unix" FkHLinux联盟
Kernel directory or unix kernel file in this directory is not found .Probably deleted during fsck or deleted by mistake .Copy it from the cdrom or restore from the backup tape. FkHLinux联盟
# cp /platform/`uname -i`/kernel/unix /mnt/platform/`uname -i`/kernel FkHLinux联盟
FkHLinux联盟
7."Error reading ELF header."? FkHLinux联盟
Kernel directory or unix kernel file in this directory is corrupted.Copy it from the cdrom or restore from the backup tape. FkHLinux联盟
# cp /platform/`uname -i`/kernel/unix /mnt/platform/`uname -i`/kernel FkHLinux联盟
FkHLinux联盟
8."Cannot open '/etc/path_to_inst'" FkHLinux联盟
System can not find the /etc/path_to_install file .It might be missing or corrupted and needs to be rebuild. FkHLinux联盟
To rebuild this file boot the system with -ar option : FkHLinux联盟
ok>;boot -ar FkHLinux联盟
Press enter to select default values for the questions asked during booting and select yes to rebuild /etc/path_to_install FkHLinux联盟
The /etc/path_to_inst on your system does not exist or is empty. Do you want to rebuild this file [n]? y FkHLinux联盟
system will continue booting after rebuilding the file. FkHLinux联盟
FkHLinux联盟
9."Can't stat /dev/rdsk/c0t3d0s0" FkHLinux联盟
When booted from cdrom and done fsck the root partition comes out to be fine but on booting from root disk this error occurs. The device name for / is missing from /dev/dsk directory and to resolve the issue /dev & /devices directories has to be restored from root backup tapes .FkHLinux联盟
