Re: 9Gb SCSI hot/swap disk for F50

[KOG]

Hi Folks,

Just wanted a second opinion as we have just purchased 9gb SCSI hot/swap hard disk and 1 gb RAM with adapter to upgrade our F50 server.

I was told by our hardware agency that to install the hard disk is easy and that there is no need to shut down the server. Is that true? I am a bit nervous when it comes to hardware that is why I am happy to install hard disk, as for the RAM memory the network manager said he will do it.

I need to check, after installing RAM is there any configuring tasks I need to do i.e. to update cfgmgr?

Thanking you all in advance.

Cheers

Katherine

HI,

On F50 the hard disks are hot pluggable.
After increasing the memory you should update (increase) the paging space,normally.
See:

hi,
when you change the memory , change your disk as well
one thing that you need to check is the firmware level of the disk
have a look at this site

You can hot plug the drive with no probelms. The memory will have to go in a specific slot but AIX will configure automatically. You should up your paging space afterward since paging space should be approx 200% of physical memory.

Paging space doesn't need to be 200% of your RAM in a lot of cases. This is dependent on your application memory usage & requirments.
We run a DB with only about 200 users, the system has 2 Gig RAM and we have 2 Gig of paging with an average paging usage of 50%, 60% max. So maybe start at the IBM recomended level (RAM +1024bytes, I think), monitor and increase if/when required.
Hope this helps. Adrian

Hi Adrian,

It alway helps to hear how other users deal with situations like this as I am the only person here with AIX and oracle experience (still learning AIX !).

I plan to install RAM sometime this week and increase paging slightly but will monitor its performance.

Many thanks to you all for your great inputs.

Much appreciated.

Regards
