Essential Dell EMC Isilon Storage Commands You Should Know
Dell EMC Isilon is a powerful scale-out NAS solution widely used for high-performance and scalable storage needs. Managing Isilon efficiently often means mastering its robust command-line interface. In this blog, we’ll walk you through some of the most useful Isilon commands to help you manage your cluster, network, storage devices, exports, and quotas.
Managing the Isilon Cluster
Change a User Password: To update the password for a user (for example, the root user), use the following command:
isi auth user modify --user=root --password=Login4Emc-123
Monitor the health status of Isilon boot drives with this series of commands that parse SMART data and life expectancy:
isi_for_array -s 'isi_radish -a /dev/ad[3,4,7] | grep -E "^Internal.|Lifetime Left|Life Remain|^Carrier board."' | awk -F '[(]' '{ if(match($0,"Life")) { printf "%s%d%s\n"," Life remaining: ","0x" substr($2,15,2),"%" } else { printf ("%s%s%s",substr($0,0,match($0,":")-1)," ",substr($0,match($0,"/")-2,6)) } }'
Alternatively, another command for detailed life percentage info:
isi_for_array -s isi_radish -a /dev/ad*|egrep 'SN:|Percent Life'|grep -v Used|sed -e 's/Percent Life Remaining:/PercentLifeRemaining %/' -e 's/Percent Lifetime Left:/PercentLifeRemaining %/' -e 's/is .*//'|awk '{print $1,$2,$3, sprintf("%d","0x"$8 )}'|sed -e 's/% 0/%0/' -e 's/ 0//'
To bulk clear resolved events from the cluster:
isi event groups bulk --resolved true
Isilon allows you to manage network interfaces grouped into pools for different workloads such as NFS or SMB. Some key commands are:
Add interfaces to a network pool
isi network pools modify groupnet0.VLAN10.NFS --add-ifaces=10:10gige-1
Remove interfaces from a network pool:
isi network pools modify groupnet0.VLAN10.NFS --remove-ifaces=2:10gige-1
Rebalance all smartconnect network pools to optimize traffic distribution
isi network sc-rebalance-all
Disk and Device Management
To format a disk on a specific node
isi devices format --node-lnn=
To add a disk to a node
isi devices add --node-lnn=
Managing NFS Exports: Add Clients to an Existing Export
Suppose you want to grant root, read-write, and general clients access to an export
isi nfs exports modify --id=34 --add-root-clients=10.234.76.145,10.234.76.146 --add-read-write-clients=10.234.76.145,10.234.76.146 --add-clients=10.234.76.145,10.234.76.146
Modifying Export Quotas: Adjust the quota settings on a directory path, such as setting a hard threshold of 2TB
isi quota quotas modify --path=/ifs/data/systemexport --hard-threshold=2T --type=directory
Conclusion
These Dell EMC Isilons CLI commands are essential for daily administration and maintenance of your Isilon cluster. Familiarizing yourself with them will help streamline management tasks from user administration to disk operations and network optimizations. Stay tuned for more in-depth guides on Isilon management!
