XP256 and RaidManager

[Bernd Reize]

Hello there,

we have two XP256's with CA for mirroring each other.
On the Host side we use RaidManager to handle PVOL / SVOL switching.
Last week, we updateted both XP's to microcode 48.06 and, to follow HP's recommendations, updated RaidManager to v01.05.03.
The problem now is: when trying to start a horcm instance, it fails. in the error log is the message:
[....]
09:24:20-be25b-08266- horcread():this device is not a command device.:/dev/rhdisk9
09:24:20-c16bb-08266- [WARNING] This device(/dev/rhdisk9) is not ready for receiving a command.
09:24:20-c56c2-08266- No device is ready for receiving a command in 1 line from HORC_CMD.
09:24:20-c857d-08266- ERROR:horcm_cfg_create
09:24:24-ed8bb-07592- horcmgr:Failed to connect to HORCM.

This message appears both on HP-UX11.00 hosts, and on AIX 4.3.3 Hosts.
Anyone knows a solution? Probably a bug in the RaidManager software?

Gruess Sie;

Do you still have a command device? Perhaps the firmware update undid the CMD dev designation. Look at the Command View or LUN Config Mgr screens to find out. The error messages are consistent with a missing CMD device.

Tschau!

Hello Vincent,

that was the first guess from our xp software consultant, too.
Badly, it doesn't work. We even installed a new CVS Volume (36MB) and declared it as a CMD Dev. Doesn't make any difference from Host side.
By the way, for testing we installed an old RaidManager (v01.03.02) on the HP-UX Hosts. What surprise! This version worked. i.E. it was able to start an instance of RaidManger. Badly the horctakeover command only produces a Core-Dump, so it is unuseable.

Thanks for your help,
Bernd

Hello,

On our XP1024 Firmware version 21-04-32 I also tried to active raid manager 1.09.04. After starting the horcm instance I recieve exactly the same error.

Cheers,

Hans
