Configuring KZPCC devices without reboot

Hi,

to minimize downtime I planned this approach.
- Build KZPCC devices using the KZPCC storage control software (windows based)
- scan and add the new devices to an existing domain
- remove the old devices
- reconfigure them using the SWCC software
- scan and add the new domains to the existing domain, too.

Problem:
Using commands like hwmgr show ... presents me the new devices, but I've found no way to get the special device files without reboot.
Question:
Is there any (supported) way to add devices with an up and running system?
How to remove the old ones?

Another question: I was told not to add devices to a KZPCC-connected shelf having a running raid-configuration. Is this true?

Any hints/pointers greatly appreciated.

Thanks in advance

Andreas

Re: Configuring KZPCC devices without reboot


If I remember correctly, the KZPCC devices are configured as shown below in the kernel config file /usr/sys/conf/HOSTNAME (even in V5.x). To obtain such entries in the config file one needs to boot from genvmunix and run doconfig.

config vmunix swap generic

bus i2o0 at *
controller i2o_bs0 at i2o0 slot 0
device disk ri0 at i2o_bs0 drive 0
controller i2o_bs3 at i2o0 slot 0
device disk ri1 at i2o_bs3 drive 1
controller i2o_bs2 at i2o0 slot 0
device disk ri2 at i2o_bs2 drive 2
controller i2o_bs1 at i2o0 slot 0
device disk ri4 at i2o_bs1 drive 4
bus isa0 at *
callout after_c "../bin/mkdata isa"
bus usb0 at *
controller comet0 at *

Johan,
that's funny but true.
ri although it is 5.1B?

Andrea,
what do you mean by scan?
hwmgr -scan scsi
?

Re: Configuring KZPCC devices without reboot

Hi,

thanks for the replies so far.
The KZPCC has a different behavior, so the devices aren't visible via the
# hwmgr show scsi
command.
The devices are usable without a reboot.
Question: How are they visible with the hwmgr command?

Regards
