Hitachi CCI (HORCM/raidcom)

Hitachi official docu: How To Debug CCI Issues

When the following error occurs during the connection test of the device

raidcom: [EX_EWSTOT] Timeout waiting for specified status

Solution:

Stop HORM instance, in this case number one

su -l xormon  
/HORCM/usr/bin/horcmshutdown.sh 1

Increase the timeout parameter (timeout(10ms)) in /etc/horcm1.conf. The default value should be 3000, increase the value to 10000.

# ip_address service poll(10ms) timeout(10ms)
localhost    11001   1000       3000
HORCM_CMD
# dev_name dev_name dev_name
\\.\IPCMD-192.168.1.1-31001
\\.\IPCMD-192.168.1.2-31001

# ip_address service poll(10ms) timeout(10ms)
localhost    11001   1000       10000
HORCM_CMD
# dev_name dev_name dev_name
\\.\IPCMD-192.168.1.1-31001
\\.\IPCMD-192.168.1.2-31001

Start HORM instance
```
/HORCM/usr/bin/horcmstart.sh 1
```
Try connection test of the device

This is most comon error after testing xormon connection to the storage:

$ ./bin/config_check.sh <Storage Name>

  STORAGE: SVPG01: VSPG
  TCP connection to "<SVP IP>" on port "1099" is ok
  TCP connection to "<SVP IP>" on port "51099" is ok
  TCP connection to "<SVP IP>" on port "51100" is ok
  WARNING : TCP connection to "<SVP IP>" on port "5110" has failed! It might need to be open on the firewall.
  VSPG Error: command failed: raidcom -login xormon    -I
  connection failed!!

1. Make sure you use proper user credential (user & password)
2. Make sure you do not use shell special characters like #!?|$*[]\{}`"'& in the password, use ;:.+-%@ instead

Error during starting of HORCM under xormon user
```
raidcom: [EX_ATTHOR] Can't be attached to HORC manager
```
Problem is that it is running under root! Stopt it under root and start it up under xormon
When that happen set user permission for /HORCM again as per adivse below, starting under root screw user rights.
```
# /HORCM/usr/bin/horcmshutdown.sh 1
# su - xormon  
$ /HORCM/usr/bin/horcmstart.sh 1 
```
Check if they are running
```
$ ps -ef | grep horcm
  xormon   19660912 1 0 Feb 26 - 0:03 horcmd_01
```

Make sure you are able to start HORCM instance under xormon

$ /HORCM/usr/bin/horcmstart.sh 1
$ ps -ef |grep horcmd_01
  xormon   14124     1  0 17:21 ?        00:00:00 horcmd_01

When it does not start then check file rights in /HORCM dir
Make sure that everything is executable and writeable by xormon user
Under root identification execute this:

# touch /HORCM/etc/USE_OLD_IOCTL
# chown xormon   /HORCM
# chown -R xormon   /HORCM/* /HORCM/.uds
# chmod 755 /HORCM /HORCM/usr/bin /HORCM/usr/bin/* /HORCM/log* /HORCM/etc/horcmgr /HORCM/etc/*conf /HORCM/.uds/

If you us commande device for storage communication in /etc/horcm1.conf then assure that stoar2rrd user owns it:

$ ls /dev/sd* | /HORCM/usr/bin/inqraid -CLI -fx
  DEVICE_FILE     PORT    SERIAL  LDEV CTG  H/M/12  SSID R:Group PRODUCT_ID
  sda             -            -     -   -       -     -       - Virtual disk

$ ls -l /dev/sdc
  brw-rw---- 1 xormon   disk 8, 0 Oct 30 10:23 /dev/sdc

Try to log on manually, this example uses /etc/horcm1.conf conf file

$ raidcom -login xormon    -I1
$ raidcom get pool -I1

Use the latest CCI, older CCI do not have to work with newer storage firmware
```
$ raidqry -h

```

restart HORCM instance under proper user xormon:

$ /HORCM/usr/bin/horcmshutdown.sh 1
$ /HORCM/usr/bin/horcmstart.sh 1

meta_resource was missing on the array for xormon user group in this case:

$ ./bin/config_check.sh <Storage Name>

  STORAGE: SVPG01: VSPG
  TCP connection to "<SVP IP>" on port "1099" is ok

Hitachi Export Tool

Hitachi official docu:
Troubleshooting Export Tool for Performance Monitor
Device Manager - Storage Navigator Messages
Run Export Tool manually to see if it works, follow this link
Make sure Export Tool installation directory and all subdirectories are owned by xormon user
```
# chown -R xormon /opt/hds
```

New Export Tool might not communicate properly with the storage SVP due to used SSL:

A possible cause is that java is started with the parameter -Del.secmode=cnsa in the Export Tool script

Check /opt/hds/<microcode>/runUnix.sh or /opt/hds/microcode/runUnix.bat file and remove -Del.secmode=cnsa from the command

Since XorMon version 1.6.15 is this workarounded automatically.

VSPG 5500 requires Java 11, it prints this error on its start if there is older Java

Export tool uses RMI and the server hostname for communication with HUS VM.
The Internet standards for protocols mandate that hostname labels may contain only the ASCII letters ‘a’ through ‘z’ (in a case-insensitive manner), the digits ‘0’ through ‘9’, and the hyphen(‘-‘).
Change the underscore (_) to hyphen(‘-‘) in hostname and issue is resolved.
In the log you see the error:

Someone else is using Export Tool at the same time.

Rebooting the Service Processor (SVP) might also help
Not all hosts being reported by XorMon NG
It worked fine since some new hosts were added, then aven after a day stats for them missing, only what helped was user rights escalation on the storage (perhaps not all rights are reuired, just noting that it resolved it)

Error: user authentication failed. The authorization header is incorrect.
Reason: User is not created.
Solution: Create user xormon on the storage, read only access
