Solution Type Problem Resolution Sure Solution 1008580.1 : Recovering from a failed FCAL boot disk
PreviouslyPublishedAs 211723 Symptoms A host that boots from a non-mirrored FCAL disk (either a Sun StorEdge[TM] A5000 or the Sun Enterprise[TM] 3500 internal disks) will have to overcome the hard-coded World Wide Number (WWN) that each of these disks uses as an integral part of their device path. On failure of the boot disk, the system administrator must ensure that this Resolution Procedure : 1) The boot disk fails and is replaced by another disk with a different WWN. 2) Boot the system into single user mode from the cdrom or network. 3) Label the replacement disk to match the slices from the failed disk. 4) Create filesystems on all the slices to be restored. 5) Mount the root filesystem and restore the data from backups. 6) Install the boot block onto the recovered root slice using the 7) With root mounted under "/a" run the following commands to re-build /usr/sbin/drvconfig -r /a/devices -p /a/etc/path_to_inst cd /devices /usr/bin/find . -print | cpio -pduVm /a/devices /usr/sbin/disks -r /a /usr/sbin/devlinks -r /a
NOTE: It is currently necessary to use both "drvconfig" and "find | cpio" NOTE: In Solaris[TM] 8 FCS or higher releases, you can use devfsadm in place of the commands in step 7 as follows: # /usr/sbin/devfsadm -c disk -r /a -p /a/etc/path_to_inst 8) Configure the "boot-device" parameter in the EEPROM using the 9) Restore the other filesystems on that disk, or comment out the 10) Reboot the system from the recovered disk. Pls take note of the above steps are applicable for Sun Fire v480 Server, Sun Fire V490 Server, Sun Fire V880 Server and Sun Fire V890 Server also.
