Re: rescan for new LUNs from EVA with Solaris
The normal procedure is to run cfgadm -al and devfsadm -c disk. Do you have any output on /var/adm/messages?
├В┬┐Is there a LUN already presented from this storage to this host?

Re: rescan for new LUNs from EVA with Solaris
Update sd.conf vi /kernel/drv/sd.conf
Add new LUN IDs created on Hitachi. (This step is not required after Solaris 9).
Instruct Solaris to re-read sd.conf
update_drv -f sd 9 and 10 can do this. 8 will failed.
Scan SCSI BUS, so Solaris can see the new luns
#devfsadm
Find new LUNs
#cfgadm -al -o show_SCSI_LUN (The added LUNS will be seen here as "unconfigured" when available)
If LUNs do not appear, server reboot will be needed.
#reboot -r ############################
