How to Recover Corrupted Linux using Veritas System Recovery 18

Good Day.

I have to test how to recover a corrupted linux system using VSR18 for linux. Below are the specs of the unit.

OS: Rhel 7.3

Disk: 2x500 GB (Raid 1)

I already peformed a backup of all volumes before corrupting the system. After corrupting the file system, the 2 disks (sda and sdb) became unknown, LVM disk (for OS) was gone. LVM disk (for swap) was also gone.

With this i would like to know if what steps i will take to recover the system.

Question

1. Do i have to partition first the unknown disks (sda and sdb)? Boot was located at the the 2 disks and create a LVM partition afterwards?

2. Was the Raid 1 Configuration already gone due to corruption?

Hi @criley

Thanks for the help.

The backup was stored in the network share (NFS).

I booted the veritas SRD and skipped to no.3 Shell.

I started the network using the command: #systemctl start network.service but it failed.

I searched for answers but unavailable to have one, i'm a newbie in linux environment.

Any inputs on how to start the network? Badly needed, few more days, i'll be deploying the system but my restoration testing is not yet OK.

@HelloHello

When you boot the SRD, one of the options during the boot process is to start networking. Have you tried that yet?

Hi @criley

I didn't see  start networking option when i booted SRD.

Please see attached file for the options i've seen.

By the way, what ports does the VSR-L 18 using?

Does below link applies to Linux also?

@HelloHello

To configure the network card/ip address, I believe you can use the ifconfig command for this.

Hi @criley

It works!

Thank you so so so much for the help!

The ff commands were carried out.

# ifconfig -a
# ifconfig etho <IP address>
//where etho is the name of network interface
# ifconfig etho netmask <Netmask>
# route add default gw <default gateway> etho
//set the default gateway
# ping <IP Address Storage>
//test the connection of the storage

 

Have a nice Day! Smiley Happy
