New rp5470 Server setup

[ajk_5]

Dear all,

I would like to tell you that I have a new rp5470 server. Right now, I am going to do a mirgation from K260 server to the rp5470 server. I concern the setup of rp5470 including users, network, security, OS parameter, etc. Would you give me some opinions how I can do it? Thanks very much!

Best Regards
Ajk

I am sure there will be a number of answers to this:

Are you using the same disks as being used in your K260? If so the interface will need to be looked at SCSI/Fibre.
If not a backup and restore.
If so, 'vgexport -p'/vgimport

Take a copy of these files:

/etc/passwd (if not trusted)
/etc/passwd and /tcb (if trusted)
/etc/group
/etc/nsswitch.conf
/etc/mail/*
/etc/rc.config.d/netconf
/stand/system (Be aware that the new system will have more parameters) (11i)
/etc/inetd.conf
/etc/services
/var/adm/inetd.sec
crontab files.
User home directories

This is for starters.

I am using all new disks in rp5470.

By the way, the K260 OS is 10.20 and the rp5470 OS is 11i.

ABout the OS, these files are mostly generic.

If it is a database, then the existing kernel parameters may change, it will depend largely upon the software and versions being used. This can also apply to patching. Generally speaking the latest will cover this area anyway.
Do you plan to use the same logical volume layout?
Are you planning a raw environment or mounted filesystems?

Hi,

since you have different OS's. I stress on creating the same file systems as it is in 10.2 and restore the data from backup on to 11i.
If you have databases (oracle or DB2)install those freshly and recover the data( using import or however you backed up) since the kernel parameter changes for 10.2 and 11i for the DB's to work.

I don't think vgexport/vgimport work in this case

Here is the K260 server:

I would like to tell you that some kind of connection between your old k260 file systems into the RP5470 would best. For there are several ways to migrate data but a file system connection between the two is always safest. This way mount the old disks and file systems into to the new server, create new vg's and copy the data over using the file system structure.

For lots of data, this would be a blessing.

Tape backup however, no problem and little effort.

How much data is there to migrate?
