Mounting SCSI Disks 1

[warmpapi]

Hi,

We have recently purchased a SUN ULTRA 450 Enterprise Server and I am trying to get it configured for Solstice Disksuite 4.2. But first, I need to have Solaris 7 recognize the 4 scsi disks. It has already recognized the first disk, bu when I try and do a fdsik or format or mount or makedev -hd it doesn't seem to work, or I am doing things wrong. Can someone help me get these disks online and recognized, please. Thanks so much for any assistance.

hui,

Hey, thanks for your help...It worked like a charm. Now I have to figure out Solstice and how I want to partition the slices and configure the metadevices, etc...Thanks again

warmpapi,
Before you go in full tilt you may want to look at the physical distribution of your disks within the 450 chassis. To use Disksuite to it's best effect you should spread them accross all the available SCSI controllers, I think it's a max of 4 on a 450. In fact DS will complain if they are not spread around and you try to introduce redundancy such as mirroring or hot sparing with disks on the same controller. I know it's obvious, but hey !

Very important time saving and disaster recovery tip, once you are happy with your disk & metadevice setup, backup the info. There is a button in the GUI, but much better to put it in the first part of your regular full system backup. We used to have a cron job that copied various system info, as well as things like /etc/hosts and the cronfiles to a space on root. This way you can restore the settings without searching through the whole backup.

Remember unlike some other disk management packages DS does not allow dynamic resizing, so make sure your volumes are going to be big enough before you commit them.

Lastly remember that you are still limited by Sun's 7 LUN rule. So you can't go and make 1000 separate filesystems as with other management packages.

Have fun Ian
