Ignite recovery

[Derek Yarger_1]

Hello guru's,

any help will be greatly appreciated, and points will be awarded!!

What on earth is the /sbin/net_cfg_prep file and what is it supposed to do?? This is an Ignite related file (I think). This file was identified by running a:

strings /opt/ignite/boot/INSTALLFS

Thanks much!

It is a part of the Ignite-UX bring up code that does _not_ get installed on the final system. It is _only_ used during the ramdisk execution time.

If you want to peek inside of *FS files ( not recommended to change them)

lvcreate -l 4 -n ifs vg00
dd if=INSTALLFS of=/dev/vg00/rifs bs=10k
mount /dev/vg00/ifs /var/tmp/ifs
find /var/tmp/ifs

That file does not exist on my systems to are Ignite servers or clients.

The location is where one would find a binary. Perhaps its a temporary file that Ignite needs during recovery.

I use these steps to see what's in IINSTALLFS:


Step 1) See that we have IINSTALLFS:
----------------------------------------------------
installfs=/opt/ignite/boot/Rel_B.11.23/IINSTALLFS
cd $(dirname ${installfs}) ; ll $(basename ${installfs})
-r-xr-xr-x 1 bin bin 36044800 Oct 7 14:42 IINSTALLFS


Step 2) Create a logical for IINSTALLFS:
------------------------------------------------------
sizeNmb=$(ls -l ${installfs} | awk '{print int($5/1024/1024+1)}')
lvcreate -L ${sizeNmb} -n IINSTALLFS_test /dev/vg00


Step 3) Copy IINSTALLFS to the logicial volume:
-----------------------------------------------------------------
sizeNbytes=$(ls -l ${installfs} | awk '{print $5}')
dd if=${installfs} of=/dev/vg00/rIINSTALLFS_test bs=${sizeNbytes}
1+0 records in
1+0 records out


Step 4) Create a mount-point and mount IINSTALLFS:
-------------------------------------------------------------------------
mkdir /IINSTALLFS_test
mount /dev/vg00/IINSTALLFS_test /IINSTALLFS_test


Step 5) Generate a listing of IINSTALLFS:
--------------------------------------------------------
ls -alR /IINSTALLFS_test
