what does this error (in syslog.log) means ??

[rveri]

Hi All ,

Got this error in syslog.log and dmesg :
Can any one please explain what is wrong and what to be done :

Thanks,

Message in the syslog are from SAN Fabric,specifically from SAN switches.
sone thing to do with Name Service at SAN End or SAN Device issues.

[Geoff Wild · Accepted solution]

Definately SAN related - did a switch change or did a FA get replaced on the Storage? Make sure SAN admin checks this out and verify's the zoning. You may have to do an ioscan -fnC disk and maybe even an insf -e

Rgds...Geoff

[Sandman!]

What kind of machine and OS version is it? Please post the output of:

# ioscan -fun -H 0/5/1/0

thanks,

You can check the NO_HW devices , comparing with your lvmtab ,

hth,
Raj.

[Sandman!]

A little more information is needed to troubleshoot this issue further...so post the output of the following commands:

# uname -a
# fcmsutil /dev/fcd2
# fcmsutil /dev/fcd2 ns_query_ports

thanks!

[mmartini]

hello...

means that someone blocked the SAN switch port on which your host was connected trought the 0/5/1 path...so your host is unable to see luns using controller c6.
Bye

Were the disks on path 0/5/1/0.98.9.19 showing up as CLAIMED before? Have any changes been made to the SAN/storage environment? a replaced card on the fabric switch or RAID controller on the storage array? If so do the following:

# fcmsutil /dev/fcd2 replace_dsk 0x620913

# fcmsutil /dev/fcd2 ns_query_ports

...if 620913 shows up in the output of the above command, run ioscan without arguments to see if the disks show up as CLAIMED instead of NO_HW.

# ioscan
