X9000 Rpc Call To Host Failed; Degrade Server Blade/Power Pic; Ibrix_Fs -C Failed With "Bad Magic Number In Super-Block - HP StorageWorks x9720 Administrator's Manual

X9000 RPC call to host failed

In /var/log/messages on a file serving node (segment server), you may see messages such
as:
ibr_process_status(): Err: RPC call to host=wodao6 failed, error=-651,
func=IDE_FSYNC_prepacked
If you see these messages persistently, contact HP Services as soon as possible. The messages
could indicate possible data loss and can cause I/O errors for applications that access X9000
file systems.

Degrade server blade/Power PIC

After a server blade or motherboard replacement, Insight Manager display on the blade chassis
may show an error message indicating that the power PIC module has outdated or incompatible
firmware. If this occurs, you can update the PIC firmware as follows:
1. Log on to the server.
2. Start hp-ilo:
# service hp-ilo start
3. Flash the power PIC:
# /opt/hp/mxso/firmware/power_pic_scexe
4. Reboot the server.

ibrix_fs -c failed with "Bad magic number in super-block"

If a file system creation command fails with an error like the following, it could be because the
segment creation command failed to preformat the LUN.
[root@eirosone1 configd]# ibrix_fs -c -f fs1 -s seg1_4
Calculated owner for seg1_4 : glory22

Iad error on host glory2
To workaround the problem re-create the segment on the failing LUN. For example to identify the
correct LUN associated with the failure above, run a command similar to the following on the first
server in the system. In the following example, server glory2 is the name of a file serving node:
# ibrix_pv -l -h glory2
PV_NAME SIZE(MB)
------- --------
d1 131070
d2 131070
d3 131070
d5
d6 131070
The Device column identifies the LUN number. The volume group vg1_4 is created from LUN 7.
Re-create the segment according to the instructions in the HP StorageWorks X9000 File Serving
Software User Guide.
After this command completes, rerun the file system creation command.
