SDD vpath mix up

[Jack Li]

I use SDD on pSerise server connect to ESS. Today I delete the vpath
and hdisk in order to fix some path in dead status. After I run cfgmgr
twice and reconfigure the vpath, I found the vpath is screw. The
status list below:

vpath0 (Avail ) 50020982 = hdisk2 (Avail ) hdisk4 (Avail ) hdisk6
(Avail ) hdisk8 (Avail )
vpath1 (Avail ) 70620982 = hdisk3 (Avail ) hdisk5 (Avail ) hdisk7
(Avail ) hdisk9 (Avail )

Hostname VG vpath hdisk Location LUN SN S
Connection Size LSS Vol Rank
-------- -- ----- ----- -------- ------ -
---------- ---- --- --- ----
server1 None vpath0 hdisk2 1D-08-01 50020982 Y
R1-B2-H2-ZA 30.0 15 0 1501
server1 None vpath0 hdisk4 11-08-01 50020982 Y
R1-B4-H2-ZA 30.0 15 0 1501
server1 None vpath0 hdisk6 1D-08-01 50020982 Y
R1-B3-H2-ZA 15.0 17 6 1701
server1 None vpath0 hdisk8 11-08-01 50020982 Y
R1-B2-H2-ZA 15.0 17 6 1701

server1 None vpath1 hdisk3 1D-08-01 70620982 Y
R1-B2-H2-ZA 30.0 15 0 1501
server1 None vpath1 hdisk5 11-08-01 70620982 Y
R1-B4-H2-ZA 30.0 15 0 1501
server1 None vpath1 hdisk7 1D-08-01 70620982 Y
R1-B3-H2-ZA 15.0 17 6 1701
server1 None vpath1 hdisk9 11-08-01 70620982 Y
R1-B2-H2-ZA 15.0 17 6 1701

You can see the disk size is differnet in same vpath.
The correct configuration should be (hdisk2 hdisk3 hdisk4 hdisk5)
belong to vpath0 ( size 30G) and (hdisk6 hdisk7 hdisk8 hdisk9) belong
to vpath1 (15G).

How can I fix it?

Thanks a lot.

I think your vpaths are just fine. You can verify by checking the
serial numbers of each vpath's hdisks using "lscfg -vl hdiskX"; you
can check the sizes of the hdisks using "bootinfo -s hdiskX".

The second output you showed came from the "lsess" command in the
ESS utils package (ibmpfe.essutil.rte). Those utils depend on a data
file that "will not be refreshed until the host is rebooted or cfgmgr
is run with all volume groups offline." (See the ESS utils README at
[url]http://ftp.software.ibm.com/storage/subsystem/tools/rd_essutil.txt[/url].)

I think lsess is just out of sync now that some hdisks were deleted
and rediscovered.
