SUMMARY: Add SAN disk without Reboot

Thanks to all who replied (original Q and list below), even without
waiting for all the fine details.
Some assumed correctly - this is an existing installation of Solaris 8
systems
using Sun-Branded Controllers...we have configured sd.conf etc
correctly.
We have 135 disks online (270 paths), and wanted to add newly-allocated
disk from the SAN.
Contrary to "support desk" advice, you CAN add disk without a reboot...

We needed to do the following
devfsadm -C
cfgadm -al     (to get a list of controllers)
cfgadm -c configure c2::500610003412EAB23141
cfgadm -c configure c4::500610003412EAB23142

After the above, the disks are visible in format, but they are
unlabelled.
Run format, scroll through the disk list, and then select the new disks
one at a time, you will be prompted whether to label Now?, answer Yes.
(It's only necessary to label the disk once, even though it has 2
paths).

THEN
vxdctl enable     (to tell veritas to look for new disks)
THEN 
vea                   (to work with them)


Thanks to all these people...

Greetings,
(Things have been working for a while, so I have been quiet :-)

Our Sun/Hitachi SAN admin allocated new disk for us,
and we are hoping to see it without a reboot.
Does anyone know if this is possible?
Archives & Google don't seem to know....

We ran devfsadm and it did not help.

drvconfig/devlinks/disks  also doesn't help, but I knew that already.

The disks will be used in Veritas Volume Manager.

Thanks in advance
Seth
