So none of those disks are bootable.
Did the system boot via the FC link which is now down?
Do you know from which disk it should boot?
It is possible that the proper boot disk is local disk0 which has sustained filesystem damage during the power cut. You may need to boot from DVD and fsck this filesystem. If that doesn't work you may need to recover some files from backup. It is likely that the FC link is down as far as the SC is concerned because Solaris isn't running and the QLogic driver isn't therefore loaded.

We will be buying new Xeon E5-based servers for our datacenter and were wondering which Fibre Channel host bus adapters we should select for these. The choices are Emulex or QLogic (8Gb FC HBAs). Anybody have any recommendations on which is the better choice?
Thanks in advance. (1 Reply)

mkbootdisk
MKBOOTDISK(8) System Manager's Manual MKBOOTDISK(8)
NAME
mkbootdisk - creates a stand-alone boot floppy for the running system
SYNOPSIS
mkbootdisk [--version] [--noprompt] [--verbose]
[--device devicefile] [--size size]
[--kernelargs <args>] [--iso] kernel
DESCRIPTION
mkbootdisk creates a boot floppy appropriate for the running system. The boot disk is entirely self-contained, and includes an initial
ramdisk image which loads any necessary SCSI modules for the system. The created boot disk looks for the root filesystem on the device sug-
gested by /etc/fstab. The only required argument is the kernel version to put onto the boot floppy.
OPTIONS
--device devicefile
The boot image is created on devicefile. If --device is not specified, /dev/fd0 is used. If devicefile does not exist mkinitrd cre-
ates a 1.44Mb floppy image using devicefile as the filename.
--noprompt
Normally, mkbootdisk instructs the user to insert a floppy and waits for confirmation before continuing. If --noprompt is specified,
no prompt is displayed.
--verbose
Instructs mkbootdisk to talk about what it's doing as it's doing it. Normally, there is no output from mkbootdisk.
--iso Instructs mkbootdisk to make a bootable ISO image as devicefile.
--version
Displays the version of mkbootdisk and exits.
--kernelargs args
Adds args to the arguments appended on the kernel command line. If this is not specified mkbootdisk uses grubby to parse the argu-
ments for the default kernel from grub.conf, if possible.
--size size
Uses size (in kilobytes) as the size of the image to use for the boot disk. If this is not specified, mkbootdisk will assume a
standard 1.44Mb floppy device.
