Redhat server not booting

Hi I am trying to get a redhat server to boot that lost connection to an iscsi san.
The ip address on the san was changed. when the server was rebooted udev errored out because it couldn't find the drives now the server is stuck at a (filesystem repair)#1 prompt. there are only a handful of things im capable of doing in this state. i tried to rediscover the iscsi drives using  iscsiadm but it won't allow me to run it. Is there a file i can edit and change the the portal address the targets are pointing to?

Thanks fo the help,
Mike

iscsi settings are stored in /var/lib/iscsi/
as files under the ifaces, nodes and send_targets
You should remove the old stuff.

Best is to boot from the rescue CD/DVD (install CD, Recue mode).
mount and chroot to your local disk and the rediscover the iscsi parameters.

ON FS maintanince mode ==>


#mount -o remount,rw /
#vim /etc/fstab


<now put a comment "#" on every FS except system FS's.. I mean those FS which are being created on iscsi's one>

:wq

#exit
#exit

System will up normally and now you can continue with further steps..

Thanks for the suggestions. Unfortunately all of the files are read only. it wont let me make any changes. I'm pretty new to linux so i have that working against me too :) It looks like i'm stuck in a basic recovery mode with out many rights to do much.

thanks

Transaction-level recovery for Oracle database

Veeam Explore for Oracle delivers low RTOs and RPOs with agentless transaction log backup and transaction-level recovery of Oracle databases. You can restore the database to a precise point in time, even to a specific transaction.

you can use
mount -o rw,remount /

to remount the rootfs r/w. Then add the /var partition if it is on a different FS etc.
and go from there.

That is what i mentioned at above..

Mike, if all are readonly then start your system in rescue mode and perform these operation by mount "/" on any temp directory.

Sorry for the delay. I got tied up with another project. the mount -o rw,remount / worked great to allow me to edit the fstab. Thanks a lot!
