FASTt, AIX problem

[jarcar]

AIX 4.3.3, fastt600

I've configured fastt600 and aix. Everytings works fine.

fscsi0 Available 1A-08-01 FC SCSI I/O Controller Protocol
dac0 Available 1A-08-01 fcparray Disk Array Controller
hdisk15 Available 1A-08-01 fcparray Disk Array Device
hdisk16 Available 1A-08-01 fcparray Disk Array Device

But then i downloaded and installed the newest device drivers

devices.pci.df1000f7.com.4.3.3.90.bff
devices.scsi.scarray.rte.4.3.3.51.bff

after reboot the new devices appears :

dac1 Available 1A-08-01 1722-600 (600) Disk Array Controller
hdisk3 Available 1A-08-01 1722-600 (600) Disk Array Device
hdisk17 Available 1A-08-01 1722-600 (600) Disk Array Device

and the old ones becomes defined
fscsi0 Defined 1A-08-01 FC SCSI I/O Controller Protocol
dac0 Defined 1A-08-01 fcparray Disk Array Controller
hdisk15 Defined 1A-08-01 fcparray Disk Array Device
hdisk16 Defined 1A-08-01 fcparray Disk Array Device


but the logical volumes defined on hdisk15,16 are missed.
The new hdisks 3 and 17 were automatically added durning system
startup. They points to the same LUN's as hdisk15 and16.

mount -a

Unable to read superblock (TERMINATED)
Unable to read superblock (TERMINATED)
mount: 0506-324 Cannot mount /dev/fastlv2 on /oracle/fast/lv2: There is
an input or output error.


Is it a way to get my lv's back ?

I suppose you had a volume group defined on hdisk15 + hdisk16 (e.g. datavg)
?

Try following commands :
...cleanup the odm
# exportvg datavg
...then read the VG definitions from hdisk17 and put them in the odm
# importvg -y datavg hdisk17
...check that you have your volumes back
# lsvg -l datavg
...and finally try to mount
# mount -a

You will still be stuck with your old (and now redundant) definitions for
fscsi0, dac0 and hdisk15+16. You can remove those if the previous steps
worked fine with :
# rmdev -dl hdisk15
# rmdev -dl ...
etc.

Just let us know how this turns out ...

Good luck,

Koen.
