InsightIQ Error: The InsightIQ user on the cluster does not have permission to view quota reports.

Error: The InsightIQ user on the cluster does not have permission to view quota reports.

Fix

1. Verify from InsightIQ server configuration to confirm the user being used for cluster connection.  Go to InsightIQ server WebUI page, and click on Settings -> Configure (click on the link associated with the cluster in question).  Check what username is being used for monitoring.  By default we use user - insightiq, If it is Different user follow the below Steps for that particular User ID instead of UserID: InsightIQ (If it a domain user, use the user id as <User_ID@Domain>).

2. Login to cli of the cluster node in question as root user.

3. Verify the current set of privileges associated with insightiq user:

//isi auth mapping token <User_ID@Domain>

# isi auth mapping token insightiq

                   User

                       Name : insightiq

                        UID : 15

                        SID : S-1-22-1-15

                    On Disk : 15

                    ZID: 1

                   Zone: System

             Privileges: ISI_PRIV_LOGIN_PAPI

                         ISI_PRIV_EVENT

                         ISI_PRIV_JOB_ENGINE

                         ISI_PRIV_STATISTICS

4. Check if any role is assigned to user account InsightIQ, If it is there; like I Bolded below; skip step 5 and go to Step 6. If no role assigned then go to Step 5

IsilonCluster# isi auth roles list --v | grep -B4 -i insightiq

      Read Only: True

--------------------------------------------------------------------------------

       Name: InsightIQRole

Description: -

    Members: insightiq

5. Create a new Role and add user to that Role

IsilonCluster# isi auth roles create InsightIQRole --description "Allows access to read and write SmartQuotas data and settings, as well as read filesystem namespace, snapshot, and smartpools information."

IsilonCluster# isi auth roles modify InsightIQRole --add-user insightiq

6. Run the following set of commands to give insightiq user additional privileges:

IsilonCluster# isi auth roles modify InsightIQRole --add-priv ISI_PRIV_QUOTA

IsilonCluster# isi auth roles modify InsightIQRole --add-priv ISI_PRIV_NS_IFS_ACCESS

IsilonCluster# isi auth roles modify InsightIQRole --add-priv ISI_PRIV_NS_TRAVERSE

IsilonCluster# isi auth roles modify InsightIQRole --add-priv ISI_PRIV_SNAPSHOT

IsilonCluster# isi auth roles modify InsightIQRole --add-priv ISI_PRIV_SMARTPOOLS

7. Verify again the privileges associated with insightiq user to make sure you see the following:

IsilonCluster# isi auth mapping token insightiq

                   User

                       Name : insightiq

                        UID : 15

                        SID : S-1-22-1-15

                    On Disk : 15

                    ZID: 1

                   Zone: System

             Privileges: ISI_PRIV_LOGIN_PAPI

                         ISI_PRIV_EVENT

                         ISI_PRIV_JOB_ENGINE

                         ISI_PRIV_QUOTA

                         ISI_PRIV_SMARTPOOLS

                         ISI_PRIV_SNAPSHOT

                         ISI_PRIV_STATISTICS

                         ISI_PRIV_NS_TRAVERSE

                         ISI_PRIV_NS_IFS_ACCESS

Logon to the InsightIQ server CLI (through Putty), and restart IIQ service with the following command:

InsightIQ# sudo /sbin/service insightiq stop

Stopping insightiq:                                        [  OK  ]

InsightIQ# sudo /sbin/service insightiq start

Starting insightiq:                                        [  OK  ]

8. Verify if the Quota Reporting page can be displayed correctly from the InsightIQ WebUI page.

In Unity Array, How to Transfer Files from the Peer SP

In Unity Array, In general only the primary SP has direct access to the network, if you want to download files from the peer SP there is no direct network access.You can access the peer SP, for file transfer, via an ssh tunnel via Putty.
The advantage of doing this, you dont need to copy files from peer SP to Primary SP.

On a Unity Array, each SP has an internal network interface named: eth_int
For SPA the address assigned to eth_int is: 128.221.255.100
For SPB the address assigned to eth_int is: 128.221.255.101

you can verify this by logging putty session into Unity with service account, and ping SPA & SPB like below



Create Session with Unity Mgmt IP <10.1.2.3> and using port 22

Go to: "Connection > SSH > Tunnels" Click "Local ports accept connections from other hosts" and create a tunnel for SPA (128.221.255.100) on tcp port 22 then Click Add Button

This is the result of clicking Add Button, Now Click on Open Button

Open up putty Session and login to the Primary SP, leave this session open.

Open Up a WinSCP session and login to SPB using 'localhost" as the address

Then transfer Your Files

Ref: https://support.emc.com/kb/499330

You can also transfer the file to primary SP, and download using FTP tools like WinSCP

Syntax:
scp your-file peer:/home/service

Example:
service@(none) spa:/home/service/> scp test_file.tar peer:/home/service

Isilon Troubleshoot Guide

Error#1 : Node's Baseboard Management Controller (BMC) and/or Chassis Management Controller (CMC) are unresponsive. Hardware is no longer being monitored

Issue : The Baseboard Management Controller (BMC) and/or Chassis Management Controller (CMC) on S210, X210, X410, NL410 and HD400 nodes can sometimes become unresponsive. When this issue occurs, the affected node may produce an event (900010011)

Resolution:

Check below version are matching, if not you need to upgrade to the recommended

BMC (Baseboard Management Controller) firmware to version 1.25 and above 

CMC (Chassis Management Controller) firmware to version 02.05 and above
OneFS version to 8.0.0.4 or 8.0.1.1 or newer

If Firmware is missing for particular Lnns, maybe that particular node is not responding, you may need to reboot the node.

How to Check BMC Version on Particular Node:
IsilonCluster1-8# /usr/bin/isi_hwtools/isi_ipmicmc -d -V -a bmc | grep firmware IPMI firmware version = 01.25

Reset BMC/CMC
- To reset the BMC on all nodes in the cluster, run the following command:
# isi_for_array -s /usr/bin/isi_hwtools/isi_ipmicmc -c -a bmc

- When this completes, reset the CMC on all nodes in the cluster by running the following command:
# isi_for_array -s /usr/bin/isi_hwtools/isi_ipmicmc -c -a cmc

- If the cluster contains HD400 or X210 nodes, also run the following command to reset the CAR:
# isi_for_array -s /usr/bin/isi_hwtools/isi_ipmicmc -c -a car

for upgrade the Firnware, refer the below KB Article Number 000466373

Isilon - The /var partition is near capacity

Issue: When the /var partition reaches 75%, 85%, or 95% of capacity, an event is logged and an alert is sent.

Fix: Rotate logs
If the /var partition returns to a normal usage level, review the list of recently written logs to determine if a specific log is rotating frequently. Rotation can resolve the full-partition issue by compressing or removing large logs and old logs, thereby automatically reducing partition usage.
Check the percentage of free isilon nodesOpen an SSH connection to the node that reported the error and log in using the "root" account.
Run the following command:
df -i |grep var |grep -v crash

Output similar to the following appears:
Filesystem 1K-blocks Used Avail Capacity iused ifree %iused Mounted on
/dev/mirror/var0 1013068 49160 882864 5% 1650 139276 100% /var

If the %iused value is 90% or higher, reduce the number of files in the /var partition using one of the methods described below:
Remove files that do not belong in the /var partition.
On the node that generated the alert, run the following command to list files in the /var partition that are greater than 5 MB:

find -x /var -type f -size +10000 -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'

In the output, look for files that do not typically belong in the /var partition. For example, a OneFS installer file, log gathers, or a user-created file.
Remove the files or move them to the /ifs directory. If you are unsure what to remove, contact Isilon Technical Support for assistance.
Determine if a process is holding a large file open

You can use the fstat command to list the open files on a node or in a directory, or to list the files that were opened by a particular process. A list of the open files can help you monitor the processes that are writing large files. See How to use the fstat command to list the open files on a node, 16648 .

If neither of the above tasks resolves the issue, continue with the following solution:
Limit the rollover file size and compress the file
Open an SSH connection on any node in the cluster and log in using the "root" account.
Run the following commands to create a backup of the /etc/newsyslog.conf file:
cp /etc/newsyslog.conf /ifs/newsyslog.conf
cp /etc/newsyslog.conf /etc/newsyslog.bak

Open the /ifs/newsyslog.conf file in a text editor.
Locate the following line:
/var/log/wtmp 644 3 * @01T05 B

Change the line to:
/var/log/wtmp 644 3 10000 @01T05 ZB

These changes instruct the system to roll over the /var/log/wtmp file when it reaches 10 MB and to compress the file with gzip.
Save and close the /ifs/newsyslog.conf file.
Run the following command to copy the updated file to all nodes on the cluster:
isi_for_array 'cp /ifs/newsyslog.conf /etc/newsyslog.conf'

If other logs are rotating frequently, or if the preceding solutions do not resolve the issue, run the isi_gather_info command to gather logs, and then contact Isilon Technical Support for assistance.

/var/log/isi_phone_home.log can grow without bound and fill up /var partition, causing issue with CELOG event generation and other operational issues with processes

Issue: /var/log/isi_phone_home.log can grow without bound and fill up /var partition, causing issue with CELOG event generation and other operational issues with processes

Cause: Log rotation does not work to auto rotate log file generated by isi_phone_home

Fix: if /var is getting too full (>85%) for any of the nodes, then run the following command:
# isi_for_array 'truncate -s 0 /var/log/isi_phone_home.log'
