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 stor2rrd
/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 stor2rrd 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 lpar2rrd  -I
  connection failed!!

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

Error during starting of HORCM under stor2rrd user (lpar2rrd on the virtual appliance)
```
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 stor2rrd (lpar2rrd)
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 - lpar2rrd
$ /HORCM/usr/bin/horcmstart.sh 1 
```
Check if they are running
```
$ ps -ef | grep horcm
  lpar2rrd 19660912 1 0 Feb 26 - 0:03 horcmd_01
```

Assure you are able to start HORCM instance under stor2rrd user (lpar2rrd on the virstuall appliance)

$ /HORCM/usr/bin/horcmstart.sh 1
$ ps -ef |grep horcmd_01
  lpar2rrd 14124     1  0 17:21 ?        00:00:00 horcmd_01

When it does not start then check file rights in /HORCM dir
Assure that everything is executable and writeable by stor2rrd user (lpar2rrd user on the Virtual Appliance)
Under root identification execute this:

# touch /HORCM/etc/USE_OLD_IOCTL
# chown stor2rrd /HORCM
# chown -R stor2rrd /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
  sdb             -            -     -   -       -     -       - Virtual disk
  sdc             CL4-A   411711   64B   -       -  000A A:00001 OPEN-V-CM
$ ls -l /dev/sdc
  brw-rw---- 1 lpar2rrd disk 8, 0 Oct 30 10:23 /dev/sdc

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

$ raidcom -login stor2rrd  -I1
$ raidcom get pool -I1

$ raidcom -logout -I1
  raidcom : User on Serial#(310444) was removed.

Use the latest CCI, older CCI do not have to work with newer storage firmware
```
$ raidqry -h
  Model  : RAID-Manager/Linux/x64
  Ver&Rev: 01-49-03/00
```
restart HORCM instance under proper user stor2rrd or lpar2rrd (on the virtual appliance):
```
$ /HORCM/usr/bin/horcmshutdown.sh 1
$ /HORCM/usr/bin/horcmstart.sh 1
```

meta_resource was missing on the array for stor2rrd user group in this case:

$ ./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

  VSPG Error: command failed: raidcom get resource -key opt -I440983
  connection failed!!
  raidcom : User on Serial#(310444) was removed.

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 stor2rrd user

# chown -R stor2rrd /opt/hds
# chown -R lpar2rrd /opt/hds  # do this on the Virtual Appliance where is all under "lpar2rrd" user

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:
```
The error "sanproject.serverux.data.SANRmiException : RMI server error (1, 5400)" 
```
Hitachi description: A different user might open one of the following windows or run the export tool. In this case, wait until one of the users moves to a different window or exits the export tool.

Someone else is using Export Tool at the same time.

Rebooting the Service Processor (SVP) might also help
Not all hosts being reported by STOR2RRD
It worked fine since soime 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)

Hitachi REST API

Error: user authentication failed. The authorization header is incorrect.
Reason: User is not created.
Solution: Create user stor2rrd on the storage, read only access
