Dear Sunmanagers,
Our suppliers installed a SUN Ultra 10 used as a firewall and there are two 9 Gb hard disks hard disks.
root@firewall #format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <ST39120A cyl 17660 alt 2 hd 16 sec 63>
/pci@1f,0/pci@1,1/ide@3/dad@0,0
1. c0t1d0 <ST39120A cyl 17660 alt 2 hd 16 sec 63>
/pci@1f,0/pci@1,1/ide@3/dad@1,0
Unfortunately they left one hard disk unused and the live hard disk {disk1) has no free partitin space. I want to utilize the other disk and mirror with Disksuite and instead of using swap for
metadb I decided to follow this procedure.
a) Configure disk2 to have an extra partition for metadb
b) Backup disk1
c) Restore to disk2
d) Modify vfstab
e) Boot on disk2
f) Repartition disk1
g) Mirror using disksuite
The problem I have is that for ultra10 the drives have to be both Master on different IDE channels. My questions are :
1) How can I know from devices path since i cannot stop and physically open the case of the ultra10 whether the disks are master, slave on primary or secondary channel ?
The devices directory is listed below :
