Possible not to specify disk name in Solaris 11 Automated Installer?

Question

Hi,
sorry if this has been asked before, I searched for it but couldn't find the answer.
In Solaris 10 jumpstart, you could use rootdisk.s0 , rootdisk.s1 to specify creating s0 on the disks. but as showing in http://docs.oracle.com/cd/E23824_01/html/E21799/gklhc.html#gllbk , when using js2ai ,
still need to use the format like:
<disk_name name="c0t0d0" name_type="ctd"/>
is it possible to just say " create 1st slice with 20g on 1st and 2nd disk , and make them into zpool mirrorred as zfs root " , because the problem different servers have different names for disks,
some are c0t0d0 , some are c0t2d0 , on some servers ,it use the long name c0t5xxxxxxxxxxx ， so is there a way to use some generic name for disks without using the actual name ?
Thanks.

Answer 1

thanks for the reply.
I do use ZFS root but still want to create slice , on a server with 4 disks (say 300G disks) for Solaris 10 , I would use the following setup:
slice 0 of each disk to be 20 G , slice 7 with rest of the space.
I would use slice 0 of disk 0 and disk 1 to be mirrored for root , and slice 7 of all the 4 disks to be the data zpool in RAIDZ. slice 0 of disk 2 and disk 3 are not used, sometimes I add them as swap if required.
I used js2ai to generate AI manifest like this :
<target>
<disk>
<disk_name name="c0t1d0" name_type="ctd"/>
<slice action="create" force="true" in_vdev="rpool_vdev" in_zpool="rpool" name="0">
<size val="20gb"/>
</slice>
</disk>
<disk>
<disk_name name="c0t0d0" name_type="ctd"/>
<slice action="create" force="true" in_vdev="rpool_vdev" in_zpool="rpool" name="0">
<size val="20gb"/>
</slice>
</disk>
<logical nodump="false" noswap="false">
<zpool is_root="true" name="rpool">
<vdev name="rpool_vdev" redundancy="mirror"/>
<zvol name="swap" use="swap">
<size val="2gb"/>
</zvol>
<zvol name="dump" use="dump">
<size val="2gb"/>
</zvol>
</zpool>
</logical>
</target>
which would work fine, the question is if how to use a generic name to replace the above "c0t0d0" disk , so the manifest would work on servers that have disks named "c2t0d0"or other names ?
Thanks
