Solution 2019544.1 : fcinfo reports No Adapters Found even with fcsm 148691-01 patch installed

Applies to:

Sun Fire V215 Server - Version All Versions and later
SPARC

Symptoms

If Solaris OS was newly installed the issue maybe OS is missing some packages/patches. Boot server from a Oracle source media, such as, CDROM/DVD then check if still have issue or not.

Initially our customer faced the output from fcinfo hba-port "No Adapters Found"

This pointed to (Doc ID 1426095.1)fcinfo Reports "No Adapters Found" and cfgadm Does Not Show FC Adapters (HBAs)

After running the Action Plan:

1. For SPARC systems:
# modload -p drv/sparcv9/fcsm
# devfsadm -i fcsm

2. Install FCSM Patch 148691-01

the problem persisted # fcinfo hba-port
No Adapters Found.

Cause

From # modload -p drv/sparcv9/fcsm we got:
can't load module: Operation already in progress

But modload grep fscm - did not show fscm loaded.

After some investigations we found a duplicate entry for fscm in /etc/name_to_major

# grep fcsm /etc/name_to_major
fcsm 309
fcsm 321

Solution

Correct the duplicate entry for fscm in /etc/name_to_major

After deleting the first (duplicate) entry "fscm 309" in /etc/name_to_major and a reboot the problem was solved.

# modinfo |grep fcsm
240 7abd8000 4cf8 321 1 fcsm (Sun FC SAN Management v20130619)
