I recently purchased a Sun Fire v20z server with two
73GB scsi discs. All original Sun parts. After istalling
the OS I was about to mirror the discs with Solaris Volume
Manager. I found out that the discs are made by different
vendors _and_ they have different geometries.
This also means I can't duplicate the partition with the
usual:
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
Partition 0 not aligned on cylinder boundary: " 0 2 00
4200768 2100384 6301151 /"
I know I could create the partitions by hand and preferably
make the a bit bigger than they are in the primary disk.
I would like to avoid this. What happens if the primary
disk fails?
Are there any other options? The disc geometries listed
below:
Vendor: FUJITSU
Product: MAP3735NC
Revision: 0108
* Dimensions:
* 512 bytes/sector
* 936 sectors/track
* 4 tracks/cylinder
* 3744 sectors/cylinder
* 38346 cylinders
* 38344 accessible cylinders
Vendor: SEAGATE
Product: ST373307LC
Revision: 0007
* Dimensions:
* 512 bytes/sector
* 720 sectors/track
* 4 tracks/cylinder
* 2880 sectors/cylinder
* 49781 cylinders
* 49779 accessible cylinders
