Can I get second system disk online without reboot 1

[mingx98]

Thanks in advance,
My boss ask me add second system disk in weekend for
our production box ( sol 2.6), but I think I can do this
online without reboot the box, so I need not work in
weekend.
Who can give a way to finish this ?

with the drive attached to the scsi bus, run the following commands:

/usr/sbin/drvconfig
/usr/sbin/devlinks

you should then be able to newfs it and mount it.

Or try

#drvconfig;devlinks;disks

This does not always work! There is no other way.

You can add the new disk to the system without rebooting by doing the following:
1> add new disk to open drive slot
2> # drvconfig
3> # disks
4> # devlinks
5> # format (choose whatever options you need)
6> # newfs
7> add mount point to /etc/vfstab to enable automount at system startup
8> # mountall (mount new filesystem, or mount <filesystem>)

This should work, I did it recently to add a new disk myself. If you have RAID implemented its a lot different cause you'll need to do a system backup, destroy the RAIDed filesystems, and re-create the RAIDed filesystems to include the new filessytem. Obviously RAID is more involved, but I'm thinking there must be a different method , isn't there always .

I'm trying to add a second IDE drive to an Ultra 10 as well. I have been through the steps mentioned above and receive no errors until I try to mount /dev/rdsk/c0t1d0s7. Then I get a:

mount: /dev/rdsk/c0t1d0s7 not a block device

I did the drvconfig, disks, and devlinks. Ran format for the device, did partition->modify->All Free Hog base number 7, verified it. No problem. newfs for this device (s7)creates a filesystem just fine. What am I missing?

By the way, newfs only works for s2 and s7, that makes sense looking at the partition table, right? Other devices give me an I/O Error.

Thanks

You cannot use partition s2 to create a filesystem, s2 is the backup partition, if you want to create a filesystem that is your entire new hardisk, just use format and configure a partition (eg: s0), to contain entire disk space, don't forget to save the new label, then to create the filesystem you can use something like:

# newfs -m 1 /dev/rdsk/c0t1d0s0

and if you want to mount your new filesystem on eg: /newdisk just:

# mkdir /newdisk
# mount /dev/dsk/c0t1d0s0 /newdisk

don use &quot;rdsk&quot; on mount (block device), use &quot;dsk&quot; block device or you receive the error &quot;mount: /dev/rdsk/c0t1d0s0 not a block device&quot;, you can also change &quot;/etc/vfstab&quot; to contain the new filesystem for eg: mount at boot time, etc.

Also when add a new disk if your are using Solaris 8, you can use &quot;devfsadm&quot; in place &quot;drvconfig,disks,devlinks&quot;, devfsadm to the job in just one command...
