This chapter describes
the Sun StorageTek 5800 system monitoring capabilities. It contains the
following sections:
Obtaining System Version and Status
1. Obtain basic cluster state information with
the sysstat command.
This command provides
an estimate of free space in the cluster that is available for data
storage. For a detailed breakdown of space usage per disk, refer to the
df command described in Getting Disk Status.
hc $ sysstat
Silo 1, Cell 1: Cluster Online. Estimated free space: 7T.
16 nodes online, 64 disks online, 0 disks unrecovered
Data VIP 10.7.225.222. Admin VIP 10.7.225.223.
Data services Online, Query Available
Failure Tolerance: Fault Tolerant
Last Recovery Cycle: Completed 5 hours ago.
Next Recovery Cycle: To complete in 9 hours.
|
The output that the sysstat command produces is as follows:
- Data services
Online means that the system is
available to read and write to, while Data
services Offline means that the system is not
available.
- Query Available
means it is possible to query and add metadata, while Query Unavailable
means it is not posssible.
- Failure Tolerance-
Fault Tolerant means the system is
operational and able to withstand failures. Failure Tolerance-
Degraded means there is one
more failure before the system loses data, while Failure Tolerance-
Not Tolerant indicates that there have been
too many failures, or the cluster is not currently online.
2. Obtain extended
cluster state information with the -v
(verbose) option of the sysstat
command.
Verbose output
includes the online/offline status of each node and disk in the
cluster. The online/offline status reported by the command refers to
the logical system status. To see the state of hardware components,
refer to the hwstat command
described in Obtaining
FRU Listings.

Getting Disk Status
1. Obtain a summary of disk usage with the df command.
The displayed numbers
refer to the logical space used by, or available for, the user's data
storage. Reserved space is reserved by the system for data recovery
operations, and is not available to the user. Total space is a sum of
Available + Used + Reserved. The use percentage is calculated as Used /
(Used + Available).
hc $ df
Logical space: Total: 18T; Available: 5T; Used: 9T; Reserved: 4T
|
2. Obtain information on
the physical space available on the disk with the -p option.
hc $ df -p
DISK-101:0 Total: 449,128,448; Avail: 361,584,640; Used: 87,543,808; Use%: 19%
DISK-101:1 Total: 449,128,448; Avail: 388,771,840; Used: 60,356,608; Use%: 13%
DISK-101:2 Total: 449,128,448; Avail: 385,692,672; Used: 63,435,776; Use%: 14%
DISK-101:3 Total: 449,128,448; Avail: 388,822,720; Used: 63,305,728; Use%: 14%

Obtaining SMTP Email Alerts
If you set up SMTP email alerts, the Sun
StorageTek 5800 system delivers email alerts for the following
conditions:
- Enabling or disabling
of a disk or server node through the CLI
- Cluster reboot
- Cluster shutdown
- Administrator
password or public key change
- Server node joining
or leaving the cluster
- Switch failover
To configure the Sun
StorageTek 5800 system to send email notifications, you must specify an
SMTP server and the email address of the recipient.
1. Specify an SMTP server
that the Sun StorageTek 5800 system will use.
hc $ netcfg smtp 10.7.224.20
|
2. Specify an email
recipient.
hc $ alertcfg add to alerts@example.com
|
Optionally, you may
also specify a cc email address, for example:
hc $ alertcfg add cc admin@example.com
